Okay, on the subject of the Scissor Sisters, I found this on a site talking about the greatest covers ever. What are these people thinking??
9 Comfortably Numb - Scissor Sisters, 2004
Orig. Pink Floyd, 1979
Only divine inspiration could explain how, or why, New York's bendiest band came to pop Pink Floyd's balloon of pretension by re-recording their most horribly self-regarding song in the style of the Saturday Night Fever-era Bee Gees. At once cold, sexy and relentlessly danceable, it far outshines the original in both concept and execution. Key moment: The flurry of electronic handclaps after the line "You may feel a little sick."
But then they do make sense here:
8 Twist and Shout - The Beatles, 1963
Orig. the Isley Brothers, 1960
The Beatles recorded their version in a single take for their debut album Please Please Me
