Why did Zac Brown Band gift cruise trips to audience members?

Well, the performance marked the band's 15th consecutive sold-out show at the venue, marking a record for the most sold-out gigs there.

And in celebration, Brown took a moment on stage to announce: "Tonight we’re going to do something that even Jimmy {Buffet} would say is crazy. I’m buying every single person here a cruise for two people on the boat. This is the biggest giveaway in history ladies and gentlemen, right here tonight at Fenway Park."

The band then proceeded to perform a rendition of 'Same Boat' - fitting.
