The southern rock group was tapped as the headliner for this year's massive New Years Eve celebration in downtown Nashville. Stapleton, who became one of country music's biggest breakthrough artists in 2015, performed his own solo set earlier in the evening to massive crowds. Those in attendance let out waves of cheers when the celebrated songwriter later joined Kings of Leon onstage for an incredible rendition of Lynyrd Skynyrd's popular track, "Simple Man."
The rather unexpected pairing generated an emotional version of the 1973 hit, with Stapleton and KOL's Caleb Followill switching off lead vocal duties. Although the rendition stayed true to the much-beloved original, the supergroup infused a gritty, yet modern sound into the track -- thanks in part to Matthew Followill's impressive guitar solos.
The memorable moment was a part of the massive New Year's Eve celebration in downtown Nashville, which also featured performances from Kelsea Ballerini and indie rockers Wild Cub. The free celebration, located on the Music City's famous Lower Broadway, drew the largest crowd in its seven-year history. According to WKRN, over 150,000 revelers were in attendance for the event.
