'Roach,
To the best of my memory the majority of the early '60's the Bee Gees were a resident act on Brian Henderson's 'Bandstand' which was a TCN9 Sydney show - along with Col Joye, Little Patti, Ray Brown and the Whispers, Billy Thorpe and the Aztecs etc - Melbourne was another world as far as the Sydney scene was concerned. We did hear Normie Rowe etc, but only as their records made the charts, at which time they might appear on 'Bandstand'. I think things started to open up from 65 onwards as the 'Rock' Shows became more acceptable to the TV audience and the need for more and more acts were needed to stop the repetition, and then we saw more of the artists from other states on Sydney TV.
Still, who knows, there are a lot of now unknown guitarists and drummers that did session work back then that we may never find out what tracks they played on and when.
