Led Zeppelin played the Schaefer Music Festival on July 21, 1969 in Central Park, NYC. This is early into the Les Paul days and the band were already recording their second album while on the road promoting their first.

I play the three opening numbers, back to back, Train Kept A Rollin, I Can't Quit You, Baby, and Dazed and Confused. Even though they're still making a name for themselves they're already famous. They'll keep rising throughout the decade to heights unimagined.
