Yep, those were the days (even though I wasn't much of a country fan then).
Hopefully, someone out there has audio of the seven-note news stinger used by CKWX (and by CFAC in Calgary) back in the '70s, as well as the redone version in the '80s as used by CKWX and CJVI in Victoria (all three stations were then owned by Selkirk, so that may have been a stinger commissioned for the Selkirk-owned stations at the time).
