After teaming with Alan Jackson for "It's Five O'Clock Somewhere," Jimmy Buffett has recorded a duet with Kenny Chesney, according to Buffett's official Web site. The track, "License to Chill," is featured in a CD-ROM bound inside Sports Illustrated's 2004 swimsuit issue. The CD-ROM also includes a teaser for the song's music video. Buffett co-wrote "License to Chill" with Nashville songwriters Mac McAnally and Al Anderson. Chesney recently updated Buffett's 1974 hit, "Come Monday," for the five-song CD, Kenny Chesney Uncovered. The Uncovered disc is available only at Target stores as a bonus with the purchase of Chesney's new album, When the Sun Goes Down
