I have a piece of guitar music stuck in my head.

[matt_doyle]

And it's driving me nuts.  Classic rock, I want to say 1970s, I cannot remember any lyrics, nor the name of the song; and I cannot figure out HOW, with just a little instrumental snippet looping in my head, I can make the Internets find this for me.

HELP.

Doo-doo DOO, doo doo DOO,  doo doo DOO doo... doo doo doo DOO, doo doo DOO, doo doo doo DOO...
