Ever discover a song because you heard it in a TV commercial

[*Wyche'sWarrior*]

Years ago, when I was a young lad, and just getting my feet wet in classic rock, Miller Genuine Draft had a commercial with "Funk 49" by the James Gang on it.  Took me a while to figure that one out during the pre internet days.  I knew it was Joe Walsh singing, but I hadn't even heard of the James Gang at that point.  Couldn't be found on any Joe Walsh or Eagles albums obviously.....by chance, I bought a compilation cassette of some classic rock tunes, and lo and behold......
