Kenny Chesney and Keith Urban rang in the new year with an impromptu acoustic jam session at a bar in the Caribbean. In addition to their respective hits, the two also provided their versions of Aerosmith's "Sweet Emotion," AC/DC's "Ride On," Buck Owens' "Act Naturally" and George Strait's "You Look So Good in Love." Urban and Dierks Bentley will join Chesney for his Guitars, Tiki Bars & a Whole Lotta Love tour kicking off March 17 in Houston.
