Was Nat Gonella's the first British recording of "Singin' the Blues"?
by David Tenner
It's at https://www.youtube.com/watch?v=ENvqHv2mgaM (which says it's from 1935, but Rust gives January 29, 1936 as the recording date). I haven't been able to find any earlier British (or indeed any non-US) versions.
Gonella is muted throughout, and seems determined not to copy Bix's solo.
