Bush were a British band that never made it so big at home, but I know they made it in the US. That song is unusual for lacking drums and having some cello instead.
I never saw Cream, but I did see Clapton at the Albert Hall and I think he played that song.
That is cool. Seeing Clapton would be awesome. I just picked up tickets for Billy Joel and Stevie Nicks the other day. I hope it ends up being a good show.
Have to see these people whilst you still can. These oldies are securing their pensions. Either doing shows or selling the music off.
