Music legends Sir Paul McCartney and Brian Wilson will team up for a one-off gig in London. MCCartney and the Beach Boys star were chart rivals 40 years ago, but are now close friends and the Beatles singer has agreed to perform at Wilson's concert at the Royal Festival Hall next month (Sep07). A source tells British newspaper the Daily Express, "Paul and Brian are good mates and as Brian is going to be performing from Pepper, the word is Paul will join him on stage one night for a couple of songs. "Paul has been long supportive and loyal towards Brian and it'll obviously be fantastic for fans to see them singing together."
