Chrissy Amphlett is Australia's female rock star — a prowling, pouty lead singer in a school pinny and suspenders with a fierce on-stage presence and a voice both husky and strong.
Before Chrissy, no Australian female singer had brought her brand of edginess to the stage — picking fights with band members, heckling the audience and channelling a serious "don't mess with me" vibe.
Wild male singers were as common as soggy beer coasters in the 1980s pub rock scene; picture the vodka-chugging Jimmy Barnes out front of Cold Chisel or The Angels' Doc Neeson hanging from stage rigging.
The voice, the drive was all Chrissy, but without what Opitz calls her on-stage "charisma coat", the girl from Victoria's Geelong was shy and vulnerable.
In an interview in 2006, Chrissy said that, for a while, "alcohol was my everything".
Then, in 2010, she was diagnosed with breast cancer.
Says Finn: "People are going to hear Chrissy Amphlett's voice again."
The whirr of a film projector fills the darkened room, and suddenly there they are: the fresh-faced Divinyls band members on the rooftop of a building in Sydney, circa 1982.
Chrissy walks past the camera and pokes her tongue out, goofing off between takes for the video clip for Only Lonely, Divinyls' second single after their debut hit, Boys in Town.
"It's fabulous," he says of the Super 8 footage he filmed and only recently discovered in storage.
By 1983, the band was touring the US, playing songs such as Science Fiction and Only Lonely from their debut album, Desperate.
