So sad to hear of the passing of #DocNeeson. Shared a few adventures with him and he was always an inspiration. You will be missed. — Aaron Harvie (@aaronharvie) June 4, 2014

Doc Neeson has passed away. True star of music in Australia. Loud when needed, and wonderful always.

Doc Neeson: How very sad. Very fond memories (well hazy) seeing Angels at ANU refectory, Captain Cook Club.
