From the Scott McKenzie website:
It is with much sadness that we report the passing of Scott McKenzie in LA on 18th August, 2012. Scott had been very ill recently and passed away in his home after two weeks in hospital.
It has been our pleasure to maintain this web site over the past 15 years and this is the hardest update of them all. Farewell our much loved and wonderful friend.
