It is not a secret but my favorite group of a cappella rockers is Rockapella (of Where in the World is Carmen Sandiego fame). They have been touring with the Boston Pops and have recently posted this message on Youtube!
So happy Decemberween to everyone! And I hope you have an upcoming awesome Christmas, Hanukkah, old New Year's, and Jeremy's Birthday. "Soon it will be Christmas day. . ."
