Shortly before joining AC/DC, Bon Scott recorded a song called Round and Round and Round will the Mount Lofty Rangers. There was also a music video.
The video is below.
This is not the first time pre-AC/DC era music featuring Bon Scott has surfaced. But, this is the group he was with just prior to joining the band he is most famous for.
He left a Mount Lofty Rangers rehearsal in a drunken rage on a motorcycle. He crashed and was in a coma for three days. He never returned to the band.
He joined AC/DC a few months later.
Scott died on February 15, 1980.
