Yeah, I saw that awful hairstyle.
I don't think it was a wig though. Just a very bad combover.
Did you see The One Show on Friday 22nd March from outside the BBC TV Centre? Wogan was being interviewed in a force-10 Gale but I couldn't concentrate on what he was saying because his lacquered comb-over (and yes it was a comb-over and not a wig) was becoming ever more vertical and more 'Bobby Charlton'-ish. I think that Chris Evans and Alex Jones were trying not to laugh.
