San Francisco band, Train, are “upset” that their song “Marry Me” was used on a New Zealand website set up in opposition to gay marriage.

The website Protect Marriage was set up by Family First New Zealand, as a site specifically opposed to equal marriage, and had featured the song when they launched.

Train have released a statement saying: “We take the idea of marriage very seriously, and believe it is the right of all consenting adults, regardless of sexual orientation.

“‘Marry Me’ is about just that, finding that special love and making it last forever. Everyone should be allowed to have that,”

Train were originally alerted by a fan on Twitter, @Mikey_J_S6: “Why does your music video appear on a homophobic lobby group’s website?”

The band responded: “Didn’t know. Getting it off ASAP. Tnx 4 tip.”

The website was launched in response to an equal marriage bill of MP Louisa Wall, pulled out of a ballot in July, and which is expected to pass when it is initially voted on this year.

On Protect Marriage, users can sign a petition against gay marriage, and read articles such as “First, Same Sex Marriage. Next, Polygamy?”
