In the late 60s to mid 70s, there was a music show on the ABC (Australian Broadcasting Corporation) called GTK, short for "Get To Know". It only ran for 10 minutes, four nights a week and for a while was pretty much the only place to see contemporary music on TV. It was assumed most of the programs had been wiped by now - but apparently not! Someone has been gathering them up and cataloging them; we can only hope there will be some sort of DVD release at some point.
Why do I mention it here?

Another episode has FC doing Polly On The Shore, though I assume that's the clip on the All Comes Round Again video.
