In spite of the successes, internal tension in the band had been growing. Phil Key and Peter Roberts abruptly left the group in September 1972 to form a new four piece outfit called Band of Light. Michael Chugg had resigned as their manager a month before the split, and they were now managed by Roger Davies. Kevin Borich, now the only remaining original member, brought in Ronnie Peel to continue the band. He retained Keith Barber and decided to carry on as a power trio. Their debut performance as a trio was at Sydney's Paddington Town Hall in November.
