Yea, Harry, I guess I was talking about two things at once (you caught me being schizoid, didn't you )
However, Zeppelin has had more covers of their music done than any other band, I think. There is even a series called "Pickin' On..." and they do Zep's music in the Bluegrass flavor (which I'm sure you would enjoy... )
I just wish Rdio.com would release their music for full streaming. Now it's preview only... and to hear any music by them you have to listen to covers.....
