Backed by former Spencer Davis Group drummer Nigel Olsson and bassist Dee Murray, John's first American concert took position at the Troubadour in Los Angeles on twenty five August 1970, and was a achievement. A stint with a brief-lived group termed the Corvettes rounded out his time. In 1974, John collaborated with John Lennon on his address of the Beatles' "Lucy in the Sky with Diamonds", the B-facet of which was Lennon's "1 Day at a Time".
