Sold! Keith Urban and Chris Janson stage the Grundy County Opry

ABC/Randy HolmesYou can just call it the Grundy County Opry, for short.

October's the month of the Grand Ole Opry’s 92nd birthday, and that’s bringing out some pretty big names, including Brooks & DunnKeith Urban and Chris Janson on Tuesday night.

Keith and Chris took advantage of the rare chance to play together, working up a special duet for the Opry stage, as you can see in a rehearsal video the Aussie superstar shared on his socials.

In the clip, the two play guitar and sing on John Michael Montgomery’s “Sold (The Grundy County Auction Incident)”. They dissolve into laughter once Chris pulls out his harmonica to play a blistering solo.

Onstage, the Keith/Chris version of John Michael’s #1 from 1995 was a huge success, as you can see from a short clip on the Opry's Instagram

“And we’re SOLD to these two on the microphone!” the Opry tweeted shortly afterward.

“Thanks @KeithUrban for this incredible @Opry moment!” Chris chimed in. “You are a class act all the way and I love you.  #GrundyCountyAuction”
