According to News.com.au, die-hard AC/DC fans have sunk to a hilarious new low in rock and roll fandom.

Fans who attended a film clip shoot in London last week were among the first in the world to hear AC/DC's new single "Rock 'N Roll Train", and, instead of leaking an unauthorized recording, have set about recreating it themselves on YouTube.

One video shows a fan dressed as Brian Johnson singing "Rock N Roll Train" in his bedroom. Another clip features a fan "singing" the song's main guitar riff in a series of "nah, nah, nah" noises.

Yet another clip shows a fan playing the song on guitar, after having the riff described to him by a friend who was at the film shoot.

Watch the clips in question below.
