On this day in 1982 – Stevie Wonder and Paul McCartney started a seven week run at No.1 on the US singles chart with ‘Ebony And Ivory’. The song gave McCartney his 24th US No.1 as a songwriter. The title was inspired by McCartney hearing Spike Milligan say “black notes, white notes, and you need to play the two to make harmony folks!”. It was later named as the tenth worst song of all time by Blender magazine and in 2007 was named the worst duet in history by BBC 6 Music listeners.
