Well, he does run a party supplies business, you know.
Still it comes as something of a surprise to see this picture of Kate's dad, Michael Middleton, joining in a conga at a Red Cross charity event on Thursday night in Belgravia, London.

Mr Middleton and his wife Carole began the night with a £350-per-head dinner at the home of one of the foreign ambassadors who hosted simultaneous dinners across London before the guests descended on the Jumeirah Carlton Tower hotel for the evening's entertainment, which incuded this conga line, according to a report in the Telegraph.
