Paul's big funny tie

The one thing that stands out to me from the press conference in Glasgow is that Paul McCartney wears this ridiculously huge tie.   I would wonder what the deal was with that goofy tie.   Was it a joke?  Did a fan give it to him?  What I learned was that Paul had purchased the tie from Harrods a few days before the tour started.   When Paul was asked where he got the tie, John Lennon said, "He leased it from Arthur English" (who apparently was a comedian at the time that was know for wearing funny ties).
