It’s always great to see behind-the-scenes footage like this!  Check out this pre-show jam session that recently took place in Houston, TX as the Brothers Osborne invited A Thousand Horses into their dressing room for an impromptu performance of Bob Wills’ “San Antonio Rose”!  Now, the description with this video said Darius Rucker was there too, but we didn’t see or hear him…do you?  If so, leave a comment below with the approximate time so we can find it!
