Train continues to find dream duet partners in Nashville. Fresh off the success of lead singer Pat Monahan's "Marry Me" collaboration with Martina McBride, Train has tapped Ashley Monroe to trade lead vocals on "Bruises," a sweet song about high school sweethearts who catch up after a decade apart -- and a decade of hard life lessons that they sweetly share with one another.

"Bruises" is featured on the iconic pop-rockers' latest album, California 37. Watch the song's video below, which features the Pistol Annies' "Hippie Annie" as a single mom and Pat as the guy who just may be after her heart again.
