I really don't think Paul McCartney wears a wig, not that's really relevant to anything. He's got a great big bald patch at the back, can't understand why you would have a wig and have a bald patch?
I don't know whether McCartney wears a wig or not, he certainly started making very dubious use of hair dye during his marriage to Heather Mills....
But on the "why wear a wig with a bald patch" question, everyone is absolutely adamant
that Terry Wogan wears a syrup, but he's got a massive bald patch at the back. So does he
really wear a wig? I don't know.
