In 1971 over a 72-hour period of time, a band comprised of 3 musicians from Flint, MI managed to completely sell out their show at Shea Stadium in New York City. Ticket sales from this event grossed over $300,000, and at the time, The Beatles held the record for the fastest sold-out show in the stadium’s history. It was none other than Michigan’s own Grand Funk Railroad who crushed The Beatles’ attendance record. This was also the first time that one American group had ever headlined at Shea. Approximately 12,000 fans camped outside of Shea Stadium in order to secure tickets the morning they went on sale, and another 9,000 fans showed up early to get their Grand Funk. Grand Funk Railroad’s incredible victory is still held in the record books of Shea Stadium to this very day.
