Thank you. IIRC, it was the jazz style to do that, unlike the classical world which of course was very staid and proper. It was the DIXIELAND jazz style, which was all about the New Orleans joie de vivre, unlike “cool” jazz which came along later. It’s all good.
While Louis epitomized New Orleans jazz, he migrated to Chicago early on (his classic West End Blues was first recorded in Chicago on Okeh records in 1928). And Chicago was the start of many jazz and pop musicians of the time. Benny Goodman, Gene Krupa, (the Dorsey bros. and Glen Miller also played in Goodman's early band as well as Harry James), Bud Freeman and the Austin High Gang, Eddie Condon, just to name a few.
