They sound more like CRC to me. The “Radiant Radio” line in the second jingle is a big clue. CRC was big with Western Canadian stations in the early to mid 1960's.
TC will most likely know what package they're from.
Thanks guys…but I have all the PAMS Demos (numbered & most of the “named” series) and all the CRC Demos (except Series #1) and it's not from any of their packages.
