John Lennon & Elton John – Whatever Gets You Thru The Night
An evening pause: This was John Lennon’s last live concert appearance, an unannounced walk-on during an Elton John concert at Madison Square Garden in 1974. And yes, that is Yoko Ono in the audience watching. At the time the two were separated, and this event apparently was crucial to getting them back together.
Hat tip Roland.
