Elvis Presley, at the tail end of his career. Tabloids reported sightings of a bloated Elvis during one of his hiatuses; there were rumors that he'd gone to the Duke University "rice diet" clinic. In those last years, you can see the diet's failure: a pot-bellied King, poured into his gaudy Vegas jumpsuit, TCB-ing his addled way through a ballad-laden set of hits, with maybe an embarrassing karate-kick or two - for old times sake - on an uptempo number.
