I like your picks, Chris, 'cept for Fred Astaire. Wow, hadn't thought about Sol Hoopii for years.

To sing along with Billy Murray, I'd throw in Henry Burr, Franklyn Baur, Charles Hart and all the other great quartette singers.

On the country side, I'd pick Carson Robison, Jimmie Rodgers, Vernon Dalhart, Frank Luther, Bradley Kincaid - what a cast!
