"The fans are a big part of what we do," says lead guitarist Angus Young and frontman Brian Johnson adds, "They are a member of the band by default".

The London set saw fans come in from all over the world to be a part of the video for the title track to their forthcoming album, "Rock Or Bust", due December 2.

"[The video] was greatly, greatly helped by the fans," explains director David Mallett. "And one chap - complete with an Angus outfit - flew from South America to watch AC/DC make a video for three-and-a-half hours�and then he flew home to South America."
