The greatest first rehearsal of all time?

In 1968, Jimmy Page, Robert Plant, John Paul Jones, and John Bonham crammed into a tiny basement room on Gerrard Street in London. Page was just trying to salvage the remains of the Yardbirds. They ripped through "Train Kept A-Rollin'" and, according to Page, immediately realized it was a life-changing musical communion. Within weeks, they were touring Scandinavia. Within months, they were recording the debut album that changed rock forever. The official "Led Zeppelin by Led Zeppelin" photo book has actual shots of these earliest gigs, showing them sweating it out in small clubs before they became stadium gods. What other band had a first rehearsal or early gig where they instantly knew they had lightning in a bottle? Drop the stories below.
