Former Watford chairman Sir Elton John says getting manager Graham Taylor to the club was one of the greatest moments of his life and he still goes "crazy" supporting the team every weekend.
The music legend spoke to Gary Lineker for BBC Football Focus in a lengthy interview about the important role the Hornets have played in his life.
He bought Watford in 1976 and, along with manager Taylor, took them from the bottom of the Football League to the top flight, where they finished second in 1983, Europe and an FA Cup final.
