VIDEO : Carrie Underwood Joins Keith Urban for a Tour in the Land Down Under

Keith Urban invites Carrie Underwood to join several of his Australian dates on the Ripcord World tour. Coincidentally, Urban and Underwood tackled the same song during their Whole Crazy Carnival Ride tour in early 2008, with Urban ? playing the part of Nicks' duet partner, Tom Petty, while also covering Mike Campbell's signature guitar leads ? welcoming Underwood back to the stage to cover the song halfway through his headlining sets.
