How good is the bass line to Lemon song!?!?! I think this track proves without a doubt that John Paul Jones was the real genius behind the group - sorry but Page just doesn't do it for me. Ever heard the phrase 'all flash no smash'....? However, Zep do seem to have an annoying tendency to just play 12 bar blues tracks that are (to their credit, effectively) disguised as straightforward rock songs - Moby Dick anyone? Or Lemon Song? Anyway, back to my point. The basis of Zeppelin seems to have been the instruments, with Planty's vocals taking second place in terms of importance. Maybe that was because of Page, Jones and Bonham's history together as session musicians. Don't know why they gave that up...they were involved with just about every early 60s recording!
