I was fairly sure it was either Iggy Pop or Billy Idol, although I checked the soundtrack of the Trainspotting movie as well.

I finally found a few versions of The Stooges with Iggy Pop singing the song I Wanna Be Your Dog.

I don't remember how and when I first heard it, but back then in the late '70's I was living in shared houses with other uni students and everyone had different tastes in music so it was an interesting way to discover new music.

It's also possible that I heard it when I worked in the local public library when we started building a music collection to loan out. The Acquisitions Librarian had an interesting, eclectic taste in a lot of new music coming out.
