Ricky Skaggs surprised fans of the Marshall Tucker Band when he joined them during their set at CMA Fest.

The band were playing an hour-long set on the Riverfront Stage, which overlooks Nashville's Cumberland River, when the 14-time Grammy winner joined them to lend a bluegrass twist to two of their biggest songs, 'Fire on the Mountain' and 'Can't You See.'

Marshall Tucker lead singer and founding member Doug Gray ended up passing the microphone over to Skaggs during the performance.

"Hearing Ricky's trademark tenor voice pierce through the air on 'Can't You See' gave me goosebumps," Gray says. "Even though our styles are a little different, Ricky fit right in with us. There was a natural chemistry up there on stage and the whole thing seems almost surreal ... It was a great day and the highlight of our year."

Skaggs says that he has been a fan of the Marshall Tucker Band for years, even though their name confused him at first.

"It was a great honor to play with the Marshall Tucker Band," he says. "I remember many years ago while listening to their first LP, I looked at the cover and asked someone, 'Which one is Marshall Tucker?' It was great to get to play some of those same songs with the band."
