U2 to duet with Blige

And speaking of performing at awards ceremonies, it's been confirmed that U2 are to perform a duet with Mary J Blige at the Grammy Awards, which take place, as you all surely know, on 8 Feb in Los Angeles. It's not been confirmed, however, which track they'll be playing, although the gossips are saying it'll be U2's 'One', which Blige did a cover of on her latest album. Can't be anywhere near as good as the Johnny Cash version.
