Jesse Fink, the author of a new book titled The Youngs: The Brothers Who Built AC/DC — feels we have seen the last of rhythm guitarist Malcolm Young in the band.

He says, “There are a lot of people out there who seem to think that Mal is going through something that can be easily sorted out, and certainly that’s not what I am hearing. As Brian Johnson said, he’s dealing with a debilitating illness.” Malcolm’s place during the band’s recent recording session in Vancouver was taken by his nephew, Stevie Young, who is also expected to tour with them.
