Band manager Grant Bartlett on Tuesday confirmed to AAP that Smith had suffered a heart attack while driving in Sydney. An ambulance arrived promptly to provide treatment but he later died.
Mr Bartlett, who has managed the Australian pop-rock band for 16 years, said Smith’s fatal heart problem came as a surprise.
“One of the healthiest guys I’ve seen,” Mr Bartlett said.
The band performed in southern NSW’s Tathra on Saturday night and was scheduled to perform in east Melbourne on Thursday.
It was formed in Sydney in August 1977 by Smith, along with Reg Mombassa, Martin Plaza, Wayne “Bird” Delisle and Peter O’Doherty.
Smith was also a vocalist, alongside Plaza, and keyboard player. He is survived by his fiancee Fiona Docker and son Harvey.
Fans are today paying tribute to the late muso:

We are extremely sad to hear about the passing of Andrew “Greedy” Smith. As a member of Mental As Anything @mentalsofficial, he was inducted into the ARIA Hall Of Fame in 2009. He was a huge character, with a big smile and boundless energy. That energy will be sorely missed. pic.twitter.com/T3rjEaXeAV

The news of Smith’s death comes just a day after the death of another respected Australian musician, Noiseworks guitarist Stuart ‘Chet’ Fraser, who died after a three-year battle with lung cancer.
