At their Aug. 2 performance at Fenway Park, Zac Brown Band made history not just with their 15th consecutive sold-out show, but with an unprecedented gift to the 35,000 attendees. Before performing "Same Boat," his 2022 collaboration with the late Jimmy Buffett, frontman Zac Brown announced that the band was buying every single person a cruise for two on Margaritaville at Sea. "Tonight we're going to do something that even Jimmy would say is crazy," Brown told the crowd, calling it "the biggest giveaway in history." The surprise is valued at more than $40 million and represents the largest audience gifting in live entertainment history, according to Brown's representatives.
