An original group called Runaway Home will take the stage Friday night at 7 p.m. as the Main Street Live summer concert series takes an Americana theme.Out of Nashville, the band is returning to the stage after playing in 2013. It was founded by three performers looking for a road back to the music they grew up on, says member Mark Elliott.“We met by chance at a small-town venue,” Elliott said. “We discovered something we had all been looking for, a three-part harmony over lyrics that matter.”Elliott, considered the “troubadour of the group,” founded the band with Gary Culley, the “guitar slinger,” and Malinda Fields.
