I thought it was him, then I thought "When the hell does he work at a catwalk show?" and assumed it must be some celebrity hairdresser who sounded like Nigel Harman.
Dave Gorman does the Homebase adverts. Shame really as he isn't at all suitable and I had a lot of respect for him until he did them. He was one of the last people I would heve expected to do an ad. We all need an income though so can't blame him.
