On Sunday, Kenny Chesney played his second stadium show in as many nights as the Brothers of the Sun Tour hit Atlanta.

The crowd got a big surprise when Georgia native Zac Brown came out on stage for renditions of “Knee Deep” and “Dixieland Delight.”

From the show wrap on Kenny’s official site:

And then there was the big highlight: Ladies and gentlemen, Mr. Zac Brown! “The thing I love most about live music is that it’s a shared moment. You never know who’s gonna show up,” Kenny said, as he introduced Brother Zac as “someone I really respect.” The two played an acoustic “Knee Deep,” then brought the band out to cover Alabama’s “Dixieland Delight.” And if anyone was prepared to doubt this crowd’s country credentials, all they had to do was take one look at what happened during the fiddle solo: the 46,000 people in this classy, urbane Georgia Dome audience kicked into one hell of a hootenanny.

Chesney moves the tour west next weekend with shows in Dallas and Kansas City. See the full schedule here.
