The lyrics to Lady Antebellum's new single, 'Dancin' Away With My Heart,' reminisce old love, which the three singers tapped into along with hit songwriter Josh Kear.

"We wrote the song on a tour bus in Florida while Lady A was on the Tim McGraw tour last year," Kear tells Taste of Country. "I was with them for two or three days during that swing, and we bounced ideas back and forth. Some were theirs and some I brought in a bit started. I had [part of] the beginning of [the song] in place."

"I finally asked you to dance on the last slow song / Beneath that moon that was really a disco ball / I can still feel my head on your shoulder / And hoping that song would never be over," they wrote in the opening lyrics.

"I actually had a different title when I first played it for them," recalls Kear. "They loved the idea immediately and almost instantly changed the title to what it is now, which was an improvement. I don't remember the original working title, but I know what we ended up with was better!"

"I haven't seen you in ages / Sometimes I find myself wondering where you are / For me you'll always be eighteen and beautiful / And dancin' away with my heart," they wrote in the chorus of the song.

"From there it was a matter of reminiscing on each of our childhood 'romances' and trying to get the emotional details right for the song," notes Kear. "In the Facebook age, it's not that hard for most people to track down or at least find out about old love affairs. But in my opinion there's a lot to be said sometimes for remembering people the way they were and what they meant to you at a particular time in your life. Who they become over time has almost nothing to do with who they were when you knew them."

"I brushed your curls back so I could see your eyes / And the way you moved me was like you were reading my mind / I can still feel you lean in to kiss me / I can't help but wonder if you ever miss me," they continued to write in the song.

"I think we knew when we finished it that this one was pretty special -- at least it was special to me," says Kear. "And hearing them sing that chorus in three part harmony on that tour bus, as always, they just kill it. Sends chills up your spine!"
