Back in the '70s, my father moonlighted as a DJ. His bathroom song was Creedence's cover of "I Heard It Through the Grapevine". That's all I can think of when I hear that song now . :lolYou know Stairway and Freebird are bathroom break songs D.J.'s will play or did play.
"Layla" was also mention upthread. I don't mind the original, but the slowed down, "Unplugged" version.... oh, how I hate that.
