As Garry’s naked buttocks crowd surfed inches from my horrified face – I thought: “no one should ever witness this”, whilst simultaneously thinking: EVERYONE SHOULD SEE THIS! Rib-splitting, vulgar, masterful. Think about that safe, warm, PG feeling your favourite Penguin novels give you – then, prepare for Gary to take that feeling and put it directly into his West End. Sounds extreme, is extreme – don’t say I didn’t warn you.
