Olivia Newton-John‘s 2007 holiday album, Christmas Wish, is a clean, low-key affair, where her versions of traditional Christmas carols — sometimes performed as duets with Jon Secada, Jann Arden, Michael McDonald, and Barry Manilow — are interspersed with brief instrumental interludes. Nothing here is too high-energy, it sometimes borders on the sleepy, but as background holiday mood music, it is effective.
