No. That was Mike Bloomfield, Dr. John and John Hammond Jr. They made one rather uninspired album in 1973, then thought better of it.

No. The married Bramletts recruited Clapton along with Duane Allman, Leon Russell and Rita Coolidge to their project, but that was after Eric had had a brief fling with some other star musicians.

Correct. After Cream said 'Farewell' in 1969, Eric and Ginger Baker joined with keyboard/vocalist Stevie Winwood and bassist Rick Gretch from Family. They toured Europe and the USA, starting riots, and recorded an album that topped the charts on both sides of the pond, forced the merger of two huge record companies, then disbanded. All in seven months!

No. Eric teamed up with Bobby Whitlock, Carl Radle and Jim Gordon from Delaney and Bonnie's band, and recruited Duane Allman to record the 'Layla' album. It proved to be their only major work as Eric was unable to complete the follow-up, owing to the death of his friend Jimi Hendrix and his withdrawal into heroin addiction.

No. But this was a 'Supergroup' formed around the same time, comprising Stevie Marriott, Peter Frampton, Clem Clempson, Greg Ridley and Jerry Shirley. Unlike most 'supergroups', they managed to stay together for more than one album, playing heavy Blues-Rock for over 20 years!
