That would be the one. His name has been changed several times throughout his career. IIRC, it started out as John Cougar, then progressed to John Cougar Mellencamp, and now it's just John Mellencamp.
Kinda bizarre, but I've always dug the cat.
Maybe the next incarnation of his name will be a hip modern version: JMell
Actually not bizarre at all. His real name is Mellencamp, he had the showname Johnny Cougar, and as his music became more real, he also took back his real name (after a fight with the record company, who was appalled at the idea. The John Cougar Mellencamp phase was a transitional compromise so that he would still be recognizable on the shelves back when there were shelves of records in real brick and mortar stores).
You are way too serious about this stuff.
