This is the final track on American country singer Brett Eldredge’s 2021 holiday album Mr. Christmas. Entertaintment Focus critic Pip Ellwood-Hughes wrote that Eldredge is “making a convincing case to be mentioned in the same breath as Michael Bublé and Mariah Carey when it comes to Christmas music” in his review of the album. “Closing track ‘O Come All Ye Faithful’ is another standout with Eldredge stripping things back so his voice steals all of the spotlight – and good lord what a voice he has,” Ellwood-Hughes continued.
There is a whole step modulation from F up to G at 2:35.
