This past weekend I saw my neighbor's daughter in her high school production of "Grease". I absolutely love Grease, so you could imagine how disappointed I was when several of the best songs from the movie were not performed (Hopelessly Devoted To You, You're The One That I Want, etc). I asked her why they were omitted, and she said the director would've loved to include those songs, but they are not part of the original staged version and that it would be "illegal" to add them and that you need special permission from that publisher, and even then it's highly unlikely it would get approved.
So my question is, why is it okay for a dance or cheer team or ice skater to pick any copyrighted song they want for their performance, but it's illegal for a play?

who is then going to want to see the original on Broadway or the touring company when it passes through town? 
Mary Rodgers, the daughter of one of the songwriters, who was alive and then owned the rights to her father's estate, had given rights for South Pacific to be performed, but wasn't informed that it had been "blended" with Hamlet. She supposedly had a cow when she heard what they did to her father's musical.
At least she didn't SEE it. There are some nightmares one can never forget.
