Background

It was apparently Jack Warner who suggested Al and Ruby work together in a film.

 

Jolson knew that About A Quarter To Nine was going to be the big hit of the picture. Harry Warren said that Al kept pestering Warren and Dubin to write an extra set of lyrics to the chorus so Jolson could cut himself in on the credit and the royalties.  
Reviews
It has everything for the box office. (Variety)
Verdict
Almost playing himself as an egocentric Broadway star Jolson turns in a great performance and the film is also helped by having the best score of any Jolson starring feature. I think this is my fave of the pre Jolson Story movies.
