“You think it’s tough out there on the streets? Try going to the theatre. That was my first reaction upon reading of a homophobic incident the other evening at the West End musical Spamalot. … This particular musical has developed – both on Broadway and, evidently, here as well – a reputation for recognisably blokeish audiences at odds with the women and gay men who make up musical theatre’s traditional constituency. But verbal abuse? That’s a new one on me.”
