Horror movie legend Sir Christopher Lee is giving fans a festive treat by releasing a collection of Christmas songs with a heavy metal twist.

The 90-year-old actor has dabbled in heavy metal over the last few years, recording several of his own albums and working with bands including Rhapsody of Fire and Manowar, as well as Judas Priest star Richie Faulkner.

Lee, who is a classically-trained singer, is now offering up a collection of holiday songs, including heavy metal covers of Little Drummer Boy and Silent Night.

The festive tracks, titled A Heavy Metal Christmas, will be available via online retailer iTunes.
