SPOILER ALERT
Okay, there isn't much difference in ACT I
Fathoms Below/Where I Belong - Seems the same as the extended version, with talks of King Triton, Mermaids, and his evil sister Ursula. Then "WIB" explains his love for the sea, it's where he feels best, and explains he wants a girl different from the rest. He doesn't want a girl, who is too primp and proper, and wishes she would enjoy sailing.
A celebration is being held at Atlantica, because Triton has defeated his evil sister. And his daughters's will sing.
Daughters Of Triton - Same as the film, just the names are sang three times. It's cute how the repeat "she's our sister Ariel", hoping maybe she didn't hear them.
The World Above - Great new song, first time we see Ariel. It's her basically telling the audience, that this is her goal. She sings about how air is so thin, and the suns so warm on her skin, how she belongs in this big bright world above.
Human Stuff - Exactly the same as the demo, and very similar to the scene in the movie. Scuttle, and his equally dumb seagull friends, explain human stuff to Ariel, all along being soooo wrong
I Want The Good Times Back - The first time we see Ursula, not my favorite. Explaining how good the old days were, before their father gave Triton his trident and made him king. And how alls she got was some magic conch shell, she didn't know how to use.
Part Of Your World - same
Part Of Your World(Reprise) - same, except no big splash at the end :@
She's In Love - Great new song! So camp. This one starts off, wondering whats with Ariel. Then the sisters realize, all from the signs. She's in love! They all sing, about how Ariel is head over fins. Then Flounder comes along, and really tears it up!
Her Voice - same as the demo, Prince Eric trying to find his mystery girl, with her haunting voice.
The World Above(Reprise) - same as the demo, King Triton forbidding his daughter to go the shore. And that humans are dangerous.
Under The Sea - Same as the film, just with a big extended dance sequence in the middle, alot like the stage version of "Be Our Guest".
Sweet Child - GREAT NEW SONG! These two reel Ariel in, telling Ariel that Ursula will help her. And end up convincing her
Poor Unfortunate Souls - Same as the film.
Act I ends with Ariel swimming to the shore, slowly her tail is coming off. It ends with her hitting the shore, taking her first breath of air, and you can see she now has legs!
ACT II
Positoovity - same as the demo, Scuttle is determined to help Ariel learn to walk. And not let her give up.
Beyond My Wildest Dreams - FANTASTIC NEW SONG! This takes place when Ariel was in the castle bath tub. Carlotta is wondering, what is Ariel thinking. And then it shows, in Ariel's head, all the stuff she is excited, and puzzled about. Some what different from the demo, more extended, and the maids sing about their dislike for Ariel. Kinda like the wash women in the movie, wondering why Eric is with this washed up mute girl, teasing that she will be good diner room conversator. Carlotta basically sings about the maids hushing up, and helping this poor child.
Les Poissons - same as the film
Les Poissons(Reprise) - just a reprise of the song, nothing different. This takes place when Ariel is served at the dining room table, and Sebastian runs a muck in there.
One Step Closer - This is great new song for Eric. It takes place after dinner, and they are on the beach. Prince Eric is showing her how to dance, and he teaches her this simple like 5 step thing. Then they end up dancing all great together, all along he is growing much closer to Ariel, and more fond of her. It ends with Ariel, ending up repeating the 5 step dance, and she smiles so happily. At the very end, you can really tell that Eric has fallen for her.
I Want The Good Times Back(Reprise) - Ursula sending out the eels because Ariel and Eric are getting too close. And that she wants the good times back.
we never see the tour of the kingdom, it just cuts to Eric and Ariel in the row boat.
Kiss The Girl - Same as the film, very beautiful on stage.
Sweet Child(Reprise) - Singing about how Ariel is S.O.L basically
If Only/Her Voice (Quartet) - AMAZING SONG!!!!!! It starts off, with Ariel in her bed. Singing about how if she could only speak, it would be some much easier. If only she could explain everything. Then it shows Eric singing about Ariel, and he starts singing about that mystery voice that is still in the back of his mind. Sebastian the reprises "If Only" saying, if only he could help Ariel, and King Triton is then shown. Singing aswell, then all four sing. All at the same time, about all the different things. Very very very moving!
Her Voice(Reprise) - Ursula singing about how Ariel doesn't have her voice.
Grimsby has come to Eric, telling him. That since he is so in love with this mysterious voice. They will hold a contest at the castle, each maiden in the land will come, and sing for Eric. So Eric can finally find the woman he loves, and get married.
The Contest - Cute silly little song, all the girls singing and not sounding like Ariel, at all! LOLOLOLOL
After all the princess preform for Eric, Ariel shows up. And she wants to try and sing for Eric. Nothing comes out, all the girls laugh at her, and she runs away in tears. Eric explains to Grimsby, that Ariel is the one he loves, because when she tried. He was hoping, let it be her, let her win, so he found out that he has fallen in love with Ariel. He goes to tell her the good news. When all of a sudden, the castle fills up with water, and Ursula comes in. And she tells Eric everything, that Ariel was the one. And how pathetic she is, that she traded all her power, and her most precious item ever, her voice, all for him.
Poor Unfortunate Souls(Reprise) - Her basically saying, poor Ariel. You now belong to me, and your time is up.
King Triton comes into the flooded palace, Sebastian and Flounder told him all about what happened. He sees his daughter with feet, and Ursula tells him what happened. He then of course, gives up his power, and Ursula gets her trident. The castle fills up all the way with water, Eric, Grimsby and Carlotta leave. Ursula is all excited, she will now rule the seven seas. Then Ariel grabs her magic conch, showing that she will crush it. Ursula says, if you break it, you will lose your voice forever. Then down from the ceiling, Eric swims down, grabs Ursula's trident. Gives it to Triton, Ariel breaks the conch, and Triton blast Ursula. And she is blasted off of stage.
The water goes down, and the palace is now hall full of water. Eric askes who Triton is, and tells him that he loves his daughter. Then, Ariel, able to speak, tells him how much she loves him. Eric askes the king, if he can have his daughter's hand in marriage, he tells him, that's Ariel's decision. They kiss, and Ariel thanks her father.
If Only(Reprise) - He explains how he gave all the merpeople their freedom, but held it back from the one he loves most. Saying, when the waves hit the shore, just think of me, when the sea mist hits your faces, it's just your daddy missing you. VERY SAD MOMENT, tear jerker!
Finale Ultimo - They sing and get happily married. Ariel and Eric are sailing the boat, while under all the merpeople are happy for Ariel.
