The band consisted of vocalist Denton Young, guitarist Brian Miller, bassist Jim Samson, drummer Kim Hunt, and keyboard player Howard Helm.
Emmett says that one of the songs he performed with Act III was "The Blinding Light Show", a tune which he later recorded with Triumph.
Zon opened concerts for The Tubes at Toronto's Maple Leaf Gardens, and for Styx and Foreigner at CNE Stadium.
After a legal battle they did manage one more album for Falcon Records called I'm Worried About the Boys!, produced by then former CBS/Epic A&R executive Bob Gallo.
Young has featured on Rik Emmett's solo work since the disbanding of Zon, whilst Hunt joined the bands Hanover, Urgent, and Moxy.
In 2003 Helm and his former Zon bandmates were contemplating a new studio album to coincide with the re-issues of that band's back catalogue on CD, but nothing ever materialized.
