Steve Grand takes it all off for charity!

Steve Grand, who became a YouTube sensation with his song All-American Boy, released another video on YouTube on Friday.

This time he wasn’t singing and he also wasn’t wearing any clothes.

But his stripping naked was for a good cause – make that three good causes.

Grand accepted the ALS Ice Bucket Challenge but because he didn’t want to waste fresh water, he decided instead to jump into a cold and dark Lake Superior.

He’s hoping his action will inspire others ‘to donate to whatever charity you feel passionate about.

‘It’s amazing what’s happened with the ALS (Lou Gehrig’s disease) charity,’ he says in the video. ‘they’ve raised so much money.’

Grand is splitting his donation three ways: to The ALS Association, to The Water Project, and to The Night Ministry – The Crib which is a local, Chicago emergency overnight shelter that accepts 20 youth a night.

Many of the youth who need shelter, Grand points out, are LGBT.
