MALCOLM Young, the Scots-born founding member of heavy metal legends AC/DC has called time on his career with the band due to a battle with dementia, reports claim.

It is understood Mr Young was admitted to full-time care at a facility in Sydney's Elizabeth Bay that is known for providing specialist treatment to suffers of the degenerative disease.

A message on the band's website said they would go on without him. Their new album, Rock Or Bust, will be released in December.

The AC/DC guitarist and songwriter's wife Linda reportedly moved Mr Young to Lulworth House, a care facility in the city's eastern suburbs.

It was announced that Stevie Young, nephew of the founding Mr Young and brother Angus, will play rhythm guitar on Rock Or Bust and will accompany the band on tour.

Young, who emigrated from Scotland to Australia at the age of 10 with his family, formed AC/DC in 1973 with his younger brother Angus, who has famously dressed as a schoolboy onstage for many years.

The band has previously survived the death of its singer when Bon Scott died in 1980 after a night of heavy drinking in London, to be replaced by Brian Johnson, who has remained as vocalist ever since.
