I have to admit I haven't always been a Miley Cyrus fan - she seemed to want to smash her "Hanna Montana" image with delight. Maybe that was a good thing. Miley is taking on a classic holiday song made famous by John Lennon and Yoko Ono after the Vietnam War cease-fire. Of course, Miley gets some serious cred by getting John and Yoko's son Sean to join in. Here's a teaser clip of the song, which is available for download or streaming right now. Enjoy. I hope Yoko is happy.
