Currently in promo mode for the re-release of his Tug Of War and Pipes Of Peace albums - the former is essential, the latter less so - Paul McCartney has dropped an eyecatching video to go with 2015 updating of his and Michael Jackson's 'Say Say Say'. With some Daft Punk-style vocodering and a new, even funkier bassline the 1983 chart-topper is likely to find a fresh audience as well as keeping Macca and Jacko's old ones happy.
