I thought that, but reading all these articles in RS got me in the mood to get the Led out, and that song was playing while I was typing and illustrated my point. I would say most people are far more familiar with the Zep version anyway.

I'm sure that is true. It is significant, however, to make the connection that the bands mentioned in the article are influenced by a band that was itself influenced and imitating other even earlier musicians.

When I discovered Willie Dixon I couldn't believe how much of his music was borrowed (stolen) by Zep and other bands.
