Allman Brothers with the Grateful Dead and members of The Band, at the legendary Watkins Glen concert in Upstate New York in 7/28/73. The largest crowd that ever gathered for a rock festival did so at Watkins Glen, New York, in July of 1973. More than 600,000 young people sardined themselves into the Watkins Glen Grand Prix Raceway for a single-day festival known as the Summer Jam featuring the Grateful Dead, the Allman Brothers, and the Band.

Each of the three groups at Watkins Glen played unusually long sets. The Grateful Dead performed for five hours, the Allman Brothers for four, and the Band for three, including a thirty-minute break due to a thunderstorm.

Prior to the concert--the day before-- we have the Grateful Dead's sound check that includes the jam into Wharf Rat or alternatively, the 1973 Watkins Glen sound check jam.
