AC/DC frontman Brian Johnson has said the band is “overwhelmed” by the success of their new album 'Black Ice'.

The record, which was released last week, is already number one in 29 countries, including the UK, US and Canada.

It is the second fastest selling album of the year in America, shifting 780,000 copies in just six days.

Johnson told the BBC: "It's overwhelming, and quite hard to take in. Even an old dog like me has a few more surprises in life, I guess."

All the more remarkable about the band's latest chart success is that 'Black Ice' is only available on CD and vinyl.

AC/DC have refrained from allowing fans to download their music in a bid to ensure their albums are purchased as a complete package.
