Welcome To ‘Beautiful Downtown Burbank’

This is the start of ‘The Tonight Show’ in Studio 1 in Burbank. The move from New York was in May of 1972 and reruns filled the gap. I think this photo is from the week prior to air as the cast and crew began a few days of rehearsal and blocking. Starting in July of ’71, guest hosts were used on Monday nights but the show was still 90 minutes long when the move occurred. Taping was at 5:30 and usually ended at 7 if there were no problems.
