Some of the biggest names in British music, including Stormzy, Robbie Williams and The Who, released a charity single on Wednesday to raise funds for people affected by the fire at a tower block in west London. The song, a cover of Simon and Garfunkel's "Bridge Over Troubled Water", also features performances from Leona Lewis, James Blunt and a large choir made up of local people, some of whom survived the blaze. The single is an initiative of pop impresario and TV talent show judge Simon Cowell.
