In 2015, Ben Francis, Kyle Hall, Lachlan Williams and Tom Russell found themselves singing '60s music in a class taught by well-known Australian cabaret performer Michael Griffiths.
It was their first taste of the spine-tingling harmonies that were so prevalent in the era.
The music class, which consisted of around 10 high-school students, rehearsed Frankie Valli's Sherry, and performed it at the 'Big Barbershop Day Out', an annual a cappella workshop held at St Peter's College in Adelaide. They received rapturous applause and a standing ovation.
A couple of weeks later, a performance opportunity arose; to sing as guests at the Adelaide Theatre Guide Awards at the Entertainment Centre. With no name, and with the belief that this would be a one-off performance, Ben, Kyle, Lachlan and Tom prepared and sang a medley of Frankie Valli's greatest hits.
The group soon realised that the iconic sound had timeless appeal, and they began exploring more music of the era, extending their repertoire and adding the sharp suits and slick choreography that were quintessential of that period.
At the end of 2016, after an extremely successful year, bass singer Tom Russell was accepted into the National Institute of Dramatic Art, and hung up his red jacket. Tom was replaced by Jordan Tomljenovic who performed with the group for their entire 2017 season. After being accepted in to the Western Australian Academy of Performing Arts, Jordan left The 60 Four in December 2017, and was replaced by Jack Conroy. In 2020, Jack Conroy was contracted to the touring production of the Book of Mormon musical, and was temporarily replaced by Finn Green. Jack Conroy returns, along with Kyle, Lachlan and Ben, for 2021.
