The Choir of St John's College, Cambridge

Iain Farrington (Organ Scholar 1996-99) performed in the opening ceremony of the London 2012 Olympic Games on 27 July. He played the piano in a comic performance of Chariots of Fire with Rowan Atkinson (as Mr Bean) and the London Symphony Orchestra conducted by Sir Simon Rattle.

"Performing in the London Olympics was a very special experience, in a sketch that combined a great orchestra and conductor, a comic genius and a stadium of 80,000 people in stitches of laughter," said Iain.

"My task was to perform the big romantic piano part as if oblivious to Rowan Atkinson's brilliantly eccentric character. Using vast reserves of concentration and plenty of rehearsal, my contribution was curiously entertaining and absurdly rewarding."

He told The Best of Hitchin, "About a week or so before the night itself, I had a technical rehearsal with Rowan Atkinson and it became clear that he's a complete professional and knows exactly what he's going to do. He didn't want to tell the rest of us what to do and just expected us to play as we normally would, so we took it very seriously and performed as professionals."
