G'day rich-joy!

Tony sang it even earlier than along with Paul Lawler and Sharon Mannix in the a cappella harmony trio CHAMELEON, from Darwin in the late 70's/early 80's; he sang it with the rest of us in Pageant in the mid 70s. From memory, Tony was the one who introduced it to us and had been singing it in the Sydney scene before I (from Melbourne - well, Steiglitz, actually - at the time) became part of Pageant.

My money is on the Wayfarers as the insigators.

Cheers, Rowan
