There's no telling who you might spot in Nashville, not only country singers, but rock singers, actors, etc. Well recently a house band was performing at Tootsie's and who joins the band on stage unannounced? The one and only Garth Brooks (thought he was living in Oklahoma) came out and sang a duet as the band covered his song "That Summer". Not only a shock to the audience, but the band didn't know he was coming out either. Music City Rocks!
