If put the 1970 Royal Albert Hall version against the early 1970s Sabbath and the 1972 Made in Japan version of Deep Purple, THAT would be a great debate (I'd pick DP...Ian Paice, baby).

The point is Zeppelin loses in all scenarios.
The most over-rated band of the 70s, though they had two really good records, they couldn’t replicate any of it on stage.
Great bands are ALWAYS great live bands.
