chas ... perhaps not for the average, capable player, but for one a step above who could read and play, there was a lot of work on Broadway, in studios, and clubs in those days ...
My M-I-L cousin was married to a professional musician - saxes, flute, clarinet, and percussion drums ... he made a good living playing all those venues as well as with the Johnny Carson Late Show band and the Merv Griffin Show band ...
BUT, those days are gone ...
