Jimmy Buffett

One Buffett agreed to write a song, Shelton immediately committed to using it as the 'Barmageddon' theme -- before he even heard it.

It's a perfect match.

Doctors told Jimmy Buffett he needs to take the rest of the year off.

Alan Jackson wasn't even second in line!

He sure knows how to enjoy the good life.

Brad Paisley and songwriter Mac McAnally were to join Buffett later this month.
