Thanks M. Ted. I've been reading this thread and trying to figure out what "trad jazz" was. So is it Dixieland your talking about, like this? [though there's no banjo]

Tiger Rag-The Original Dixieland Jazz Band

"The Original Dixieland Jazz Band was the first (white) jazz band to record in 1917. The band stayed together for years and their last recording was done in 1936.
The band members went for different careers. However some record producer tried to get the band together again some 10 years later.
Therefore I assume that this clip was produced in the mid forties after trumpet player Nick La Rocca organized and found the original band members for this event".
