IN Lambeth is a glowing triumph that makes you remember why you go to the theatre. William Blake (Gregory Gudgeon) sits naked up a tree with his wife Kate (Sonia Beck) discussing archangels and rabbit pie when a breathless Thomas Paine (Chris Tranchell) knocks on the yard door. Director Karla Goodman draws out the magic in a startling meeting of social revolution and personal revelation that carefully jumbles the prosaic, the humorous and the deeply profound.
