I was in the weight room yesterday and a LZ tune was playing. I'm pretty sure it was LZ...sounded a lot like Plant's voice. Anyway, I'm not sure of the title. I didn't catch any of the lyrics so I search that way. The only thing I remember was that it had a little piano part to it: quater note, quater note, eigth note. This would play, Plant would sing, switch to a chorus, and then the cycle would repeat. It was a pretty upbeat song. My friend said it was possibly 'No Quarter' or 'Misty Mountain Hop.' I know it's not the latter and have not heard the first. Any ideas?
