''Equus'', ''Waiting for Godot'' and ''A Mid-summer Night's Dream'' – three very distinctive plays, and my favourite three, out of which you won't often get me choosing just one. But were I to do so, it might actually be the last, for the simple reason I would delight in playing any and all characters from it. Yes, I know Hermia and Helena look a bit implausible now – but I put it to you stranger things happen on stage… Some of the strangest things involve a player himself, a lowly actor who gets given an ass's head and is forced to be the enamoured of a fairy queen. It's this section of the play that this book concentrates on, in quite stunning form.
