Get Happy! is such a great album.
The bass work in this song was always some of my favorite: the tone Bruce gets is the ideal Platonic form of what a P bass ought to sound like. And it's a driving bass line while also also keeping melody around the vocals and it's mixed so out in front which just makes me feel all warm and fuzzy inside.
I've always loved how Elvis layered his vocals on his albums as well - doing his own backup vocals and singing over himself and it just works so well and is something that always stuck out to me as somewhat unique about him.
Anyways, here's the song - King Horse
