The veteran musician was asked to take on a role backstage at the London musical shortly before Christmas (25Dec15) by giving out presents that actors and crewmembers had bought for each other.

Brian donned a Santa suit for the occasion and his wife Anita dressed as "Mrs Santa", and he shared pictures of the couple in costume in a post on his website.

"Well, here's me and my dear and wonderful missus being Mr and Mrs Santa backstage at the Vaudeville Theatre..." he writes. "The occasion was the Secret Santa celebration of the London cast of Kinky Boots. Their Company manager, Heather, is an old and dear friend of mine, and she asked us if we'd appear as a surprise, to distribute the presents..."

In return for giving out the presents, Brian was gifted a pair of high-heeled red boots as seen in the show, and he shared snaps of himself wearing them.

"As the curtain came down on a very well-received show, we were kitted out with boots from the show," he adds. "These things are no casual accoutrement. Each pair is worth about two thousand pounds, hand-made by a specialist company for the show... This was the first time I'd ever experienced trying to stand up and walk in 5 inch heels and platforms... I can tell you I now have a new respect for anyone who can make a success of this kind of thing. The cast of this show not only sty (stay) upright in these things for 2 hours and a half, but manage to dance in them too... Amazing. I can still feel the pain!!!"
