Felt this could be an interesting topic, seeing so many songs I like actually have earlier versions I'd never previously heard of. Here's the ones I can think of off the top of my head:
Hooked on a Feeling by Blue Swede
I Fought the Law by the Bobby Fuller Five (or the Clash)
The Tide is High by Blondie
Real Wild Child by Iggy Pop
Last Kiss by the Cavaliers
It's So Easy by Linda Ronstadt
I Love Rock and Roll by Joan Jett and the Blackhearts
All Along the Watchtower and a whole lot of other Dylan songs
Then there's the rare instances when a person or group covers their own songs, like Leaving on a Jet Plane by John Denver, or I Saw Her Standing There and Do You Want to Know a Secret by the Beatles.
