Talking of collaborations with hip-hoppers, the lovely Madness have done that very thing with UK rapper Sway on a new single. 'Sorry' is out 5 Mar, but you can currently preview it on the band's MySpace page - http://www.myspace.com/madnessofficial.
Sway, who says further collaborations with Madness may be in the pipeline, comments: "I've always wanted to do something with them; it's an honor for me."
