The Greatest Bits: B-Sides & Rarities is the second compilation album released by the British pop rock band McFly. The album was released on 3 December 2007, and was only available at Woolworths stores in the UK. The album has a range of B-sides and covers from the group's singles, as well as a new recording of "Santa Claus Is Coming To Town". Physical copies of the album have become quite sought after since the collapse of Woolworths in 2008 although it has since been released on downloads. The cover version of "Pinball Wizard" is a new live version, previously released only as a studio version and a music video.
