@clacke @methoddan have also listened to "Jimmy Carter" many times, never knowing (and being too lazy to look up) what Grammy, Gordy, and Geordie refer to. Maybe because of that I was never 100% certain whether it was a homage, or some kind of obscure satire. In any case, definitely one of the catchiest free culture tunes.
p.s. that track was the very first thing that popped into my head upon seeing a headline about the person's health. All the best to Jimmy, friends, family.
