Dur­ing Sat­ur­day night’s “Vir­tual Real­ity Tour” stop in Den­ver, Brad Pais­ley called home­town hero Time Tebow (who was watch­ing the show with broth­ers and friends) to the stage.  The Den­ver Bron­cos quar­ter­back was brought on stage prior to Brad per­form­ing “I’m Still A Guy,” and Tim helped Brad, doing a sur­prise duet for the unsus­pect­ing crowd. Brad tweeted “‘Still A Guy’ has never been so excit­ing. Or quite so beau­ti­fully off key.”
