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.
