AC/DC founding member and rhythm guitarist Malcolm Young passed away earlier today at the age of 64 after battling dementia for several years. Alex Lifeson commented on Young's passing via a post on the official Rush Facebook page:

"Finally, peace comes to Malcolm. His guitar playing will endure for generations to come and that is a worthy legacy." - Alex Lifeson

Rush played a short string of shows with AC/DC opening back in November of 1977 on the A Farewell to Kings tour, including one show at the Onondaga War Memorial Auditorium in Syracuse, NY exactly 40 years ago today. RIP Malcolm Young.
