Size, as we all know, isn't everything. Unless it's The Right Size, of course. Sean Foley and Hamish McColl: are they a comedy couple or a theatrical troupe? Frankly, my dear, I don't give a damn. I do know that Do You Come Here Often? is daft, delirious, dreamy, downright silly and defies all expectations of what a comedy about two men stuck in a bathroom should be. I am not alone in this. People small and large, wet and dry have flooded in through the doors of their Edinburgh Fringe venue, the Lyric Hammersmith and the Vaudeville Theatre only to stagger out afterwards beaming with pleasure at the physical virtuosity, the beautifully crafted outlandishness and the boundless good humour of these two. Later this year, they'll be up to no good (I'll be bound) at the Almeida in a Brecht play, but their West End triumph has just been extended until the end of next week. On no account miss out.
