Longtime Pals Jimmie Allen and FOR KING + COUNTRY Team for the First Time on ‘CMT Crossroads’

Jimmie Allen and hit-making Christian duo FOR KING + COUNTRY are the latest collaborators on the popular “CMT Crossroads” series, PEOPLE announces exclusively.

Their hour-long concert, to be televised Feb. 28, marks the first time the three artists have shared a stage, but given their history, you have to wonder: What took them so long?

Allen and the duo, brothers Joel and Luke Smallbone, have been friends since meeting at a studio about 14 years ago when all three were unknown, unsigned and struggling for a toehold in the Nashville music community.

Over the years, the three have stayed tight as they’ve all risen to the top of the charts, but they never had any collaborative opportunities — until now. When CMT reached out to Allen, 37, with the “Crossroads” invitation, he says, “Joel and Luke were the first call.”
