Wayne Duncan of legendary Australian band Daddy Cool, has died, aged 72.

Duncan was a major reason why Daddy Cool was so cool. His death comes nine months after guitarist and fellow Daddy Cool founding member Ross Hannaford died. Duncan suffered a stroke last week. Only days before he was playing live and had upcoming shows booked.

A friend of Wayne Duncan, Craig Horne, released a statement on behalf of the Duncan family.

"It is with deep sadness that I let you know... that our great friend Wayne Duncan passed away in the early hours of this morning," Mr Horne wrote on Facebook on Sunday.
