Yes, it is Peter Andre.
I played Sandy in Grease for a school assembly. When I tell people this they tend to assume that I went to public school and will tell me that William, the head of internal catering at their law firm, also started out in drag at school. Every other Thursday, depending on the clients being entertained, the firm will let William serve lunch as Wilhelmina. Usually in something dropped waisted and decolletée with his hair done up like Zsa Zsa Gabor. One of the senior partners insists that being in drag makes a difference to William's food cooking - the seasoning's more tangy on the Thursdays when he's Wilhelmina. And William got into doing drag at Eton, playing Mabel in a Heads House production of The Pirates of Penzance. It being an old boys public school of course, some boys will be cast as girls.
I will then clarify that I went to a comprehensive school, and that it was mixed. But aged twelve I was the only pupil at Archbishop Michael Ramsey with both the high notes for "Hopelessly Devoted to You" and the cleavage for "You're the One that I Want".
