Listen to Jack Johnson on iHeartRadio | Listen to The Roots on iHeartRadio

Jack Johnson is doing his part to help the relief effort in the Philippines with a laid-back take on a Christmas classic.  He teamed up with the Roots on Monday's "Late Night with Jimmy Fallon" to put a new spin on "Rudolph the Red-Nosed Reindeer." 

Johnson and the band all donned matching red sweaters for the performance, but the "red" theme doesn't stop there. 

The track is now available to download on iTunes, with all profits going to the Red Cross to benefit the organization's work in the typhoon-ravaged Philippines.
