I'll grant cheerfully grant you Mr. Sun/Mr. Moon was a neat tune but as for the rest, most of them never got air time locally. A lot of that was due to two factors. First the local D-J's had a pre-approved list of music that they could draw on. Even if there was a heavy write in vote for certain songs, the spin jockeys would only play them if the title was on the list. Second, that list was generated by the Bureau of Broadcast Standards, aka, "The Bureau of Canadian Broadcast Censorship". Basically, to get a license, you had to adhere to the mandated standards for what types and styles of music were deemed acceptable for listeners. While you got to listen to a wide spread of musical choices, up here, unless in a highly urban area, not so much. All whole lot of early rock and roll and related genres got denied air time because the "Censors" thought it would cause unacceptable social behaviour in the young people. Since the censorship board was composed of mostly moral morons and bible thumpers, along with a bunch of career bureaucrats with the social inertia of Mount Fuji, pretty much what got the most air time was the soggiest excuse for music available, think polka and superannuated big band and crooner stuff. What made it worse was that a lot of good music material was also critical of the war in Nam and Canadians didn't "officially" take part in that action. ( Factoid of sorts here; for every draft dodger that jumped our border, somewhere between 1-2 Canadians slipped over going the other way to enlist. So there was something of an offset there. And if you got caught trying to cross to enlist, you caught hell from the federal government and justice system for trying; which didn't stop a lot of them from making multiple attempts. Hey, when we believe, We Believe.)
So anyway, much of the later music of groups like the Raiders never did get local air time.
