Beatles' icon Sir Paul McCartney is reportedly set to record a charity single to combat both testicular cancer and whichever X Factor ballad attempts to secure the Christmas No.1 spot.
According to the Sun (who gave it the headline 'Maccas Xmas Tracka for Jacka'), McCartney is one of a number of celebrities taking part in a cover of A Great Big World's 'Say Something' for Samuel L. Jackson's cancer charity One For The Boys.
The Sun reports that at an event hosted by Radio One DJ Nick Grimshaw, soul singer Jennifer Hudson will also appear on the song, as well as Game Of Thrones actress Maisie Williams and model Daisy Lowe.
