From www.myspace.com/jasonmraz and YouTube:
Jason took some time away from recording his studio album to put together a “little something special” group of gospel songs for the holidays for his Grandma Mraz. While recording for Nanny ‘Raz he took a moment to put this holiday greeting together for you, Happy Holidays 2007 from Jason!
No matter what kind of religious beliefs you identify with, you can’t not like the powerful sound of a gospel choir, and this group is amazing. Also, nobody rocks an old man sweater like our Mraz. Mmm, mmm, Christmas cozy.
