Country a cappella group Home Free made their debut at the Grand Ole Opry on Friday night (July 17) -- and instantly earned an invitation to come back.

The five-man group sang their own versions of Tom Cochrane's "Life Is a Highway" and Johnny Cash's "Ring of Fire." They received a standing ovation at the end of their performance, and Opry Vice President and General Manager Pete Fisher invited them to return for another appearance.

“We were overwhelmed by the crowd's response during our debut at the Grand Ole Opry," Home Free member Tim Foust says in a press release. "We were just honored to be among country royalty ... We never imagined we would receive multiple standing ovations and get invited back on the spot!”

Home Free's most recent release is an original song, "Crazy Life." The Season 4 winners of The Sing-Off released a music video made with Lego figures for the tune.

"Our "Crazy Life" video turned out better than we could have possibly dreamed,” band member Austin Brown notes. “It really is such a good time … we had a lot of fun with this song and the Brotherhood Workshop’s interpretation of our miniature, Lego-selves.”

Crazy Life is also the title of Home Free's latest studio album, which was released last year.

Home Free will be spending the remainder of the summer on the road, including a series of shows in Canada next month. A complete list of dates is available on their website. The quintet will also be appearing on a track on Kenny Rogers' upcoming Once Again It's Christmas album, scheduled to be released later this year.
