Brad Paisley and John Mayer are the latest artists meeting for CMT Crossroads. The two will share the stage in a one-hour concert to be taped March 30 in New York before an invitation-only audience. Mayer was just 22 when he emerged in 2001 with Room for Squares, a debut album containing the hit "Your Body Is a Wonderland." Paisley and Mayer should prove to be an interesting combination, especially considering that both are young singer-songwriters who also happen to be formidable guitarists. Their CMT Crossroads episode is scheduled to premiere in May.
