UK jazz/blues singer George Melly still does "Frankie & Johnny" with actions but when he was younger and slimmer he used to "die" at the appropriate point by throwing himself off the stage & landing in a paratroop roll before climbing back to finish the song. In some venues getting back was more difficult and the band had to "vamp till ready" for some time for his reappearance. Will Hastie, reeds player for a time with one of the many versions of the Temperance Seven, used to do a "Roland Kirk" , playing two penny whistles simultaneously , one with each hand (NOT taped together pace the tw thread!), but no doubt that is old hat to folk pw players. Jesse "Lone Cat" Fuller, of course was a tremendous blues one man band and on one track he adds simultaneous tapdancing and guitar playing to his multiple skills. Lenny Hastings, much missed drummer with the Alex Welsh Band wore a terrible syrup (wig) and when he had a few drinks taken often climaxed a drum solo by whirling it round on one of his drum sticks. I'll draw a veil over his Adolf Hitler/Richard Tauber impressions... Not folk, though, sorry!
