The show was originally scheduled for 13 March 1976. However, the ticket was printed before the tour was confirmed, and the concert date was then booked for 17 April.

Then the 17 April date was postponed. The reason for the show's second postponement was because keyboardist Ken Hensley left the band and flew back to London on 17 April. Hensley was fed up with singer David Byron's drinking problem, and planned to quit the band. Uriah Heep's manager Gerry Bron convinced Hensley to return to the band and give Byron one last chance to sober up. Hensley returned to the tour, and the Boston show was re-scheduled for 6 May.

The Boston show was the last night of the 1976 US tour, and the last US show with David Byron in the band. Byron continued with the band for their European tour before he was fired from the band due to his drinking problem. Byron's last show with Uriah Heep was at Sportspalace, Bilbao, Spain on June 25, which was John Wetton's last show as well.
