Elton John was joined on stage by John Lennon at Elton's Madison Square Garden concert. They performed three numbers together, "Whatever Gets You Through the Night", "Lucy in the Sky With Diamonds" and "I Saw Her Standing There". Lennon had promised the flamboyant rocker that he would make a stage appearance with him if his "Whatever Gets You Through the Night" became a #1 hit, which it did two weeks earlier. Later that same night, Lennon and his estranged wife Yoko Ono reconciled backstage after being separated for a year.
