The Young family is 8 siblings. George who helped found AC/DC as producer (formerly of the Easybeats) died a few weeks ago. Malcom was suffering from dementia when he left the band 4 years ago. Here's some Malcom moments. His rhythm guitar was like a well oiled machine. Truly the backbone of the band. His nephew Stevie took over the reins. Malcom gave him the thumbs up and thought he had what it took.
