A new Tribute CD comes out on March 18th called "Sleepytime Tunes: Jimmy Buffett Lullaby Renditions".
From what we have found out so far the CD contains lullaby version of some of Jimmy’s greatest hits including the songs "It’s 5 O’Clock Somewhere", "Margaritaville", and "Cheeseburger In Paradise".
(thanks to Tom for passing that along to us)
