It’s true what they say—you never know who you might catch performing in Nashville.  

The one and only Garth Brooks dropped in and sang a few songs at Tootsie’s Orchid Lounge on Broadway Thursday night.  

Brooks shocked Andy Gibbons, who was performing on the honky tonk’s second floor when the superstar jumped in for a performance of his hit “That Summer.” 

Just more proof that you never know who you might see here in Nashville.
