Australians - and New Zealanders - are paying tribute to Stevie Wright, widely regarded as Australia's first international pop star, after he died aged 68.
He became a superstar at the age of 16, as lead singer of iconic 1960s rock band The Easybeats.
Their song, 'Friday On My Mind', became a global hit and was voted the best Australian song ever in a 2001 poll.
The group broke up after five years, but their music was later covered by David Bowie, INXS and many others.

If you guys haven't listened to the Easybeats, you're missing out. They're one of my all time favorite bands. Stevie Wright was amazing. RIP— Dylan Gardner (@dylangardner) December 27, 2015
The Easybeats were a true international success of which Australia could be justifiably proud. #RIPSteveWright— Michael Byrnes (@MichaelByrnes) December 27, 2015
Friday On My Mind is a straight-up banger – maybe the best song by any Australian, ever #ripsteviewright— Elle Hunt (@mlle_elle) December 28, 2015
Battling drug and alcohol addiction, he underwent electric shock treatments and "deep sleep therapy" - medically induced comas - in the 1970s, that left him with long-term after-effects.
The Sydney private hospital that treated him was later the subject of a Royal Commission after dozens of patients died.
He passed away in hospital on Sunday night.
