Saw it years ago but don't remember much about it. Not very familiar with that song, actually. I only remember hearing it sung by males and thought some of the lyrics might be a problem. Heck I really don't know, maybe Gershwin wrote it for a woman originally, and I've been hearing an altered version.
Jean Louisa Kelly stole the move "Mr. Holland's Opus" with her sultry version of "Someone to Watch Over Me" by merely changing "he" to "she" in the lyrics.
