Zac Brown Band surprised more than 37,000 fans at their sold-out Fenway Park show in Boston on August 2 by giving everyone in attendance a free Margaritaville at Sea cruise for two. Margaritaville at Sea is also a presenting sponsor of Zac Brown Band’s current Love & Fear Tour, which continues through November. Between “Toes,” “Knee Deep” and now thousands of fans headed on vacation, Zac Brown Band may officially be taking the beach-country lifestyle to another level.
