Luke Combs is releasing a long-awaited song to country radio this Friday. The singer is dropping “5 Leaf Clover” on St. Patrick’s Day. Combs has been teasing fans with the song for nearly two years. It will also appear on his forthcoming album, ‘Gettin’ Old,’ which is due out on March 24th. The 18-song collection serves as a bit of a counterpart to his ‘Growin’ Up’ album that he released last year.
