Long Live Wock 'n' Woll
Yeah, but then one has to wonder which song will be used for each band. Probably the most everplayed/overrated ones naturally. Dare to take a guess as to Led Zeppelin or Deep Purple's selections?
Smoke On The Water has nearly nothing to do with what Deep Purple are able play, I suppose Black Night will be an ultimate classic rock song in this case.
On Led Zep I would think between Black Dog and Heartbreaker. Stairway To Heaven shouldn't represent the band IMO.
