Has anyone else ever checked the keys of songs sung in movies, where a singer actually asks for a song to be played in a certain key. Over the years we have. We've found many where the requested key is not the one used for the song. We had a list once but it went astray. Two very obvious examples we remember from musicals are:

In the film - Show Business
Eddie Cantor sings - "Curse of a Broken Heart"
Asks for it to be played in the key of E.
Then it's played in D.

In the film - Singing in the Rain
Debbie Reynolds sings - "Singing in the Rain".
Asks for it to be played in the key of Ab.
Then it's played in E.

These are lines delivered by singers. They must have noticed. Is this a movie in-joke? Hildebrand is a keen movie buff. He's never seen this mentioned in a movie book or review. Any one else noticed? Cheers, Joy
