[3] The film includes commentary from Jimmy Barnes, Daryl Braithwaite, Celine Dion, Tommy Emmanuel, Brett Garsed, Graeham Goble, Bev Harrell, Richard Marx, Olivia Newton-John, Robbie Williams and Glenn Wheatley.

Reviewer Jim Schembri notes "A fitting, lovingly made tribute to a singer who evolved into the definitive Australian pop artist...a very good, richly detailed biographical documentary that chronicles Farnham's stellar, decidedly bumpy career.

"[8] Sandra Hall from Sydney Morning Herald gave the film 4 out of 5 stars saying "Reality rarely produces biographies that fit neatly into three acts, but John Farnham's life so far is a stirring exception.

It's a story with everything – laughter, tears, love and rock 'n' roll... [and the documentary] captures it all, with Farnham's large roster of friends taking an obvious delight in reminiscing about times spent with a man they both like and admire.

"[9] Peter Gray from The AU Review gave the film 4 out of 5 stars saying "'Finding the Voice' finds the love for its subject and envelops his presence, and in a day and age where talent is fleeting and prominence is temporary, there's a warmth in being reminded of longevity and the facility behind it.
