I would like to recommend the following:
Fountains of Wayne - "The man in the Santa Suit" Trust me, it's excellent!
BB King - "Christmas comes but once a year"
Smashmouth - "You better Do It Right"
Bob Rivers - "Decorations" (Beach Boys "Good Vibrations" parody)
Bob Rivers - "Santa Claus is Foolin Around" (a bit racy, and hilarious)
Kiri is the only big name opera star, I have never seen or heard in person. A few years ago, I was in Vancouver and saw a poster for her farewell concert and reading futher, I discovered I was two days too late.
