After Warners spent a lot of money restoring Jolson's Mammy (for DVD distribution), only to have it sink back into oblivion, I suspect we won't be seeing any other of his films on Blu-ray now that The Jazz Singer got its release.I restricted the titles in my initial post to films that were favorites of mine. Afraid I never cared for "Go Into Your Dance". Don't find much charm in Jolson - and Ruby Keeler, adorable as she can be, definitely needs a leading man that's not just talented but likeable too (like Dick Powell) to help her get her through the ins and outs of any given screenplay with some degree of dramatic plausibility.
But if this is a title you're after, I hope Warmer Archive eventually comes through for you.
Solid agreement, by the way, on the fact that the two songs you mentioned are standout pieces of classic 30's pop.
