I saw Bo Diddley doing one of these kinds of shows toward the end. I’m sure he needed the money.
Eric Burdon of The Animals fame still tours pretty much constantly, a prisoner of the road. He now does his show sitting on a stool, and really isn’t very good anymore, IMHO. From what I heard, none of the The Animals except Alan Price got “a bean” for their efforts, as it all went to their manager and Price, who got sole credit for arranging House of the Rising Sun. According to Burdon, it was a group effort, but he said that guitarist Hilton Valentine’s arpeggio lead-in was the real key to the whole thing, the thing that grabbed you right off.
