[Lonesome in Massachussets]

Big bands were always economically problematic. Part of the problem was an FDR wartime “nightclub tax” which contributed to the demise of the big bands. Hollywood and the recording industry could provide the economies of scale to justify big bands, but popular tastes changed to smaller ensembles. I bet the Stones got more per performance than any of the big bands ever did.

There was a post about that here in March. How the Taxman Cleared the Dance Floor (How a 'cabaret tax' brought the decline of Big Band Music)
