who sang "Red Headed Woman" (song in Harlow film)?

I know I asked this of John awhile back via personal email, but he wasn't sure. If anyone has seen the film "Red Headed Woman" from 1932, I have been trying to find out the name of the singer and band performing this song -- it appears in the nightclub sequence. They show the band, and the singer, and it even appears that the musicians have sheet music. According to imdb.com, the song was written by Raymond B. Egan and Richard A. Whiting, but I have yet to find someone who knows who performed it! Even if it was being lipsynced in the film, clearly a real singer had to have sung it and a real band had to have performed it -- it's a neat song and I'd ideally like to find it on 78 if it actually exists in that form. The other possibility is that is was performed strictly for the movie, but it is a pretty catchy song and it just seems like it might have been released on record. Anyone know this song?
