The London Gay Men's Chorus (LGMC) will release a cover of Bridge Over Troubled Water to benefit the victims of last week's mass shooting in a gay nightclub in Orlando.

The choir will release its version of Simon & Garfunkel's hit on Friday.

Proceeds from the sale of the song will benefit the Pulse Victims Fund and Galop, a London-based group which works to reduce hate crimes directed at the UK's LGBT community.

Forty-nine people died and dozens were injured when a lone gunman opened fire in the Pulse nightclub.

The choir performed the single at a packed vigil last week in London to remember the victims. Footage of the performance went viral.

“The attack on the Pulse nightclub in Orlando sent shockwaves through the whole LGBT community,” said LGMC artistic director Simon Sharp. “The LGMC responded in the only way we could: through song.”

Sharp said that the response to the performance was “overwhelming.”

“We were truly overwhelmed by the public response to our performance at the Soho vigil and want to do everything we can to raise money for the victims of the Orlando attack and for victims of LGBT hate crime in the UK,” Sharp said.

The release is will be available for purchase on all major digital platforms.
