"What you doing later?" Little Big Town's Phillip Sweet asks Luke Bryan as Bryan comes over to his side of the stage and gives him a hug in this video. No doubt a tour of friends, Bryan and Sweet joked with each other before they began a cover of Ed Sheeran's "Thinking Out Loud" at a recent tour stop in Pennsylvania.

“All right, check this out. If you cannot hook up in the next six minutes … you have got no game,” Bryan told the audience in State College, Pa., before joining Little Big Town on the song.

While Sweet sang the first verse, LBT's Jimi Westbrook and Bryan could be seen mimicking the song's lyrics to each other at the left side of the stage while Karen Fairchild and Kimberly Schlapman danced along.

The sultry song had each of the five singers trading lines and harmonizing for a unique cover. While the audience roared in approval, Bryan noted that something very important was missing.

"We need some tequila," he said mid-song.

Tiny red Solo cups of shots of tequila were then passed out to the singers and Bryan toasted all the birthdays in the room.

"Here's to getting in your birthday suit tonight!" he joked. "All right, let's dim the lights. Dim the lights."

Meanwhile, Little Big Town continue to pass around a bottle of tequila and each take a swig (some more than others — we're looking at you, Westbrook!) before the supergroup joined forces for another memorable cover. This time, they segue into Marvin Gaye's appropriate "Let's Get It On."
