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!

Danny Reagan gets a bit starry-eyed when he spots the singer, but then things take a turn for the worse.

Kenny Chesney joined him on stage for his most famous song.

He later satirized the incident in a song.

He sure knows how to enjoy the good life.

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

It's hard to believe he has never played on the hallowed stage.
