Train'Hey, Soul Sister' hitmakers Train recently stopped by our Los Angeles studio for a very special holiday-themed AOL Sessions. The full performance launches Tuesday, but we have a behind-the-scenes exclusive for eager fans.

Pat, Jimmy and Scott let our crew follow them throughout the day as they snapped photos, tuned up and rocked out in the studio. Check out the candid video below and be sure to tune in tomorrow for the full Sessions set.
