Australian rock band AC/DC is set to announce their retirement, media reports say.
Entertainment reporter Peter Ford told Melbourne radio station 3AW on Monday that the band may never perform or record again.
Perth radio 6PR said the split was the result of illness, amid speculation that Malcolm Young was unwell.
Ford later tweeted that more details on the split would emerge shortly.
The rumour mill extended soon after to adding that this was due to a terminal illness.

@donnademaio there is a sad story behind all this that I have chosen not to report ...boys played together privately a few weeks back

As FasterLouder points out, James Young, owner of Melbourne's Cherry Bar (situated on AC/DC Lane) and band aficionado, revealed on a Facebook post not long after the news broke that he's also heard such rumours, intimating that Malcolm Young is too sick to perform due to a smoking-related illness.
"Weeks ago I heard something I kept to myself. The band got together for 40th anniversary show rehearsals and Malcolm had forgotten how to play guitar.... due to a clot on the brain caused by smoking.
"I hope and pray this isn't true and that Malcolm Young will be OK because Malcolm Young is the engine room of the greatest tough rock n roll band the world has ever known.
Reports that the band has a booking at a Vancouver studio on May 1 - again rumoured rather than definitely known from the band, which has never bothered with giving regular updates on its movements for the benefit of the media - both contradict and yet leaves open the possible truth of the rumours.
The booking may suggest a new album is on the cards but it's also possible that circumstances have changed since the studio booking.
Albert Music, the headquarters for AC/DC in Australia since 1973, is virtually in shut down mode to media enquiries. No one is taking calls or answering emails, let alone talking. This may be a sign they are as blindsided by the rumour as anyone else and/or trying to confer with the band members and management based overseas.
Or it could be they were caught short before the official announcement and are working out a new media strategy.
