I did a search on Amazon for old musicals from the 30's & 40's and only came up with "42nd Street". I'm looking for the Busby Berkley extravaganza musicals, Fred Astaire musicals, "Broadway Melody of..." musicals, etc. I have several of these on VHS and am looking to replace them with DVD versions. So far, it doesn't look like many are out there. Any rumors of these old films getting the DVD treatment?
