I would think there may be a couple of members left from The Drifters ( but I have not looked up Obits ). Performers from the 1930s are going to be pretty young then and fairly old now, maybe a recording Parrot or Two ? Bands may still be going though personnel have changed - Military and Dance bands, and I suspect a few artists from the1960s cut demo , acetate or local record booth 78 discs in the 1950s or a bit later before they got famous.
