Oak Ridge Boys Join Home Free for Cover of ‘Elvira’ [Watch]

The legendary Oak Ridge Boys have joined with country a capella group Home Free for a unique cover version of one of their signature hits, "Elvira."

The new rendition of the classic song — which reached No. 1 on Billboard's Hot Country Singles chart and No. 5 on Billboard's Hot 100 all-genre chart in 1981 — features the four members of the Oaks along with the five members of Home Free for a fun, harmony-rich arrangement that appears on Home Free's forthcoming Country Evolution album. The project also features Charlie Daniels collaborating with the group on his signature song, "The Devil Went Down to Georgia."

“This is a pivotal year for Home Free,” bass singer Tim Foust says in a press release. “We’re coming into Country Evolution fresh on the heels of our Grand Ole Opry debut. We’ve gotten to collaborate with music icons such as the Oak Ridge Boys and Charlie Daniels. We’re excited to say the least.”

Home Free debuted on the Opry in July and earned a strong reaction from the crowd. Opry Vice President and General Manager Pete Fisher personally invited them to return.

“We were overwhelmed by the crowd’s response during our debut at the Grand Ole Opry,” Foust recalls. “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 also appear on Kenny Rogers' upcoming Christmas album, Once Again It's Christmas. They are set to release Country Evolution on Sept. 18 via Columbia Records. The album is currently available for pre-order on iTunes and Amazon.
