And Clapton Didn't Even Know

I'll have to listen to Change of the Century again to fully appreciate this. I know Cream's live playing pretty well and I think they had few equals--probably none in their time. A few years later the Mahavishnu Orchestra kicked up a similar amount of dust, but there were five of them and the bass player stuck to the bassics.

Um...McVie also played in the Bluesbreakers with Clapton, no?

Marty, McVie is on the cover and on the record: The band on this album includes Mayall on piano, Hammond organ, harmonica and most vocals; bassist John McVie; drummer Hughie Flint; and Clapton. Augmenting the band on this album was a horn section added during post-production[citation needed], with Alan Skidmore, Johnny Almond, and Derek Healey (misrepresented on the sleeve as 'Dennis Healey').

Oops, sorry Marty--I didn't read subsequent posts before re-posting!

That may be true--however, the music discussed here is from the 60s. His addiction was in the 70s.
