I don't know if it's the one you want but the chorus to the one I've heard (I think it was at Buntingford) is :

My proper name is Clarence, but you can call me Clair
I wear sexy underwear and per-ox-ide my hair
My politics is Liberal, my outlooks liberal too,
Between you and me dear, I'm a little bit queer,
But I've taken a fancy to you
