Singer and angry vegan Morrissey says that his show at Madison Square Garden on June 27 will be totally meat-free, which is news to MSG vendors, according to the New York Post.

Rolling Stone published an open letter Morrissey wrote to Al Gore and other organizers of Live Earth, a series of international benefit concerts for climate change research, in which he implores them not to let vendors serve meat or dairy at the concerts, as factory farming is a known major contributor to climate change.

Morrissey writes:

Serving meat and dairy products at an event to combat climate change is like selling pistols at a gun-control rally. Your responsibility is to alert people to a crisis, not sell out to the vendors responsible for it.

Not only is it possible for venues to provide a 100 percent meat-free menu-as is done now at every concert venue in which I perform, including Madison Square Garden, where I have a show at the end of June-it’s also a moral duty.

Morrissey is serious about this: he threatened to cancel a 2013 concert at L.A.’s Staples Center if his meat-free demand was not met, to which the arena sort of acquiesced, closing McDonald’s and expanding vegetarian options.

One MSG staffer was skeptical that the arena would carry it out, telling the Post, “We’d have to close half the floor.”

But Drew Nieporent, a Morrissey fan with a good attitude, said he’d close the burger stand he owns.

“We’ll just go and enjoy the music,” he said, because “Morrissey can do what he wants.”

Meat Is Murder” remains the Smiths’ worst song.
