How far is too far? That’s the question which underlies the nihilistic versifying of Bobby Spade, white-suited barfly bard, the laureate of oedipal self-loathing who swims in a miasma of misogyny. Spade is the deeply strange, deeply funny creation of Phil Nichol. In this show the no doubt decent Nichol doesn’t get a look in. Where Rich Hall brings on his alter-ego Otis Lee Crenshaw in the second half, Nichol comes on as Spade and goes off as Spade. And, boy, does he go off.
