If you ever get a chance to check out The Black Jacket Symphony performing Zeppelin, jump on it. They will be in Lexington in January. They'll usually cover a full album, but this time it looks like they are going to cover random Zeppelin tunes. I saw them perform the entire Led Zeppelin 4 album, and they were outstanding.
I like all the songs that had already been recorded by other bands, then Zep recorded their own version and claimed as their own. Those are all really great.
