AC/DC guitarist Malcolm Young 'too ill to play live'

AC/DC guitarist Malcolm Young is "unable to perform any more" due to illness, according to a friend of the musician.

Mark Gable, the frontman with fellow Australian group Choirboys, claimed that Young "will probably not be able to record" any more.

However music magazine Billboard has said there is "no truth" to rumours that AC/DC will be forced to retire.
