Yoko Ono and The Flaming Lips have collaborated numerous times in the past, including a “Late Show with David Letterman” performance and a four-track joint EP that contained the holiday tune “Atlas Eets Christmas.” Now, they’re back with another Christmas song, this time opting to cover John Lennon’s “Happy Xmas (War Is Over).” Ono and the Lips pepper Lennon’s classic with a little psychedelic energy, giving it enough oomph to distinguish it from the original without straying too far from its peace-willing charm. The cover is part of Amazon Prime’s 43-track holiday compilation, “All Is Bright.”
