The Greatest Bits: B-Sides & Rarities is the second compilation album released by British pop rock band McFly. The album was released on 3 December 2007, and was only available at Woolworths stores across the UK. The album features 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". The record has become quite sought after since the collapse of Woolworths in 2008. Also, their cover of "Pinball Wizard" is a new live version (previously released only as a studio version and a music video).
Mr Brightside is a song covered from "The Killers", originally taken from the bands performance in the Radio 1 Live Lounge studio. Dougie Poynter also takes lead vocals. This originally was on the "I Wanna Hold You" single.
Umbrella is a Rihanna cover which McFly first performed on their Greatest Hits Tour and then a recorded version was placed on "The Heart Never Lies" single, produced by Danny Jones.
Pinball Wizard is a cover of a song by The Who, who McFly collaborated with in 2005 on "My Generation" (the charity single). A studio version featured on "I'll Be OK" single, but here the song is performed live.
"Deck the Halls" was a B-side for "Room on the 3rd Floor" single, with Dougie Poynter on lead vocals.
Fight For Your Right is a Beastie Boys song covered, which McFly performed first on the Motion in the Ocean Tour, and then the live recording of "Fight For Your Right" was a "Transylvania" B-side. This version features here.
