The Drapers Arms three nights ago - Michael Palin.
Crikey, I thought it was a weird conjunction between Tris39, Michael Palin and Boak&Bailey for a moment, however it's a different The Drapers Arms; maybe Cider Drinker and DaveM could be involved if such a thing ever happened.
Cheating a bit as I wasn't in a pub, rather standing next to me at the check-out queue at the Oxford Street branch of M & S: Kenneth Cranham (likes his cardies does our Ken).
