I got a question to anyone who knows old/classic rock.. theres a song I heard a longggg time ago, it always stayed in my head, but I have no clue who sings it or the name of the song, it sounds somethign like led zepplin..
it starts off with a weird harmonica like solo while the guy is singing something about someone leaving him..
like I said, its a long time I haven't heard this song.. anyone have any ideas?
Thanks
Shaun
