Moody Blues bassist John Lodge has been in the studio putting the finishing touches on his new album, 10,0000 Light years Ago, which will be out on April 14th. While in there last week he performed an impromptu acoustic version of “The Spirit of Christmas.”

A post on his Facebook page says, “There are many veterans out there that credit Johns and the Moody’s music for getting them through tough times…so as a salute to these brave heroes, John is donating all proceeds from the sale of the song to the Wounded Warrior Project.”

This version of the song, which was originally released on The Moody Blues’ December album in 2000, is available on iTunes.
