'Late Show' host and avid country music fan David Letterman has invited Tim McGraw to stop by his show twice in one week for what will be very special concert events. Tim will perform Oct. 12 and Oct. 16 on 'The Late Show With David Letterman,' followed by mini-concerts billed 'Live on Letterman,' which will be broadcast on the CBS website and on CBS Radio country stations. Tim is only the fourth artist in history to have a concert hosted by 'The Late Show,' following Paul McCartney , Pearl Jam and Elvis Costello.

These shows are part of a whirlwind media tour supporting Tim's upcoming album, 'Southern Voice,' which hits stores Oct. 20. You can hear his 'Live on Letterman' performances online, on KILT radio.
