zac Brown and Jimmy BuffettThe Zac Brown Band are dipping their toes into the water and their ... butts ... on stage as they team up with the King Parrothead, Jimmy Buffett for an upcoming installment of 'CMT Crossroads.' They'll tape the show before an invitation-only audience next month in Nashville, and the episode will premiere in March.

The two acts will trade vocals on each other's songs, which could include some of Jimmy's sun-and-sand-inspired tunes such as 'Margaritaville,' 'Come Monday,' 'Cheeseburger in Paradise' and 'Fins,' as well as Zac's chart-topping hits, 'Toes,' 'Chicken Fried' and 'Whatever It Is.'

Previous 'Crossroads' pairings include Taylor Swift and Def Leppard, Bon Jovi with Sugarland, Reba McEntire and Kelly Clarkson and Kenny Chesney with John Mellencamp.
