Jip it's easy when you got a shit load of money to give a little away

AC/DC frontman Brian Johnson has lashed out at charity work done by Bono and Bob Geldof, saying they should do it in private.

In his only Australian interview, the outspoken singer said he and his Grammy-winning band prefer to help in private with no press conferences.

"I do it myself, I don't tell everybody I'm doing it," Johnson said.

"I don't tell everybody they should give money - they can't afford it.

"When I was a working man I didn't want to go to a concert for some bastard to talk down to me that I should be thinking of some kid in Africa.

"I'm sorry mate, do it yourself, spend some of your own money and get it done. It just makes me angry. I become all tyrannical."
