The 60 Four’s Studio 64 moves beyond the group’s original ’60s and ’70s focus to span seven decades of music. Four vocalists and a live band perform songs associated with Frankie Valli, the Bee Gees, Queen, Elton John, Michael Jackson, Robbie Williams, Backstreet Boys, Bruno Mars and John Farnham. The show retains the group’s vocal harmonies, choreography, humour and live musicianship while broadening its repertoire. The act formed in Adelaide in 2015 when four high-school students bonded over vocal harmony, and has since become an internationally touring live act.
