Summer Jam at Watkins Glen was a 1973 rock festival that drew more attendees than any pop music festival before it. An estimated 600,000 fans flocked to the Watkins Glen Grand Prix Raceway outside of Watkins Glen, New York, to see performances by The Allman Brothers Band, The Band, and the Grateful Dead.
