Your "clarinette" post just jogged my mind and I think that my 8-Track was branded Clarion (new model in the summer of 1971).
I sold the 67 bug to a distant cousin in the early summer of 77 and when he brought it back Aug/Sept so that I could teach him how to set the timing (trial and error by driving/adjusting it as it no longer performed optimally when set to spec with a static light) he had an 8-Track "convertor cartridge" for the player that accepted cassette tapes.
I had purchased a new Honda Civic with radio only (just sold my 69 Opel GT that had a cassette deck as I needed a "bigger" car to move to the West Coast) and gave him all of my "road" cassette tapes.
We didn't realize that we were "distant kin" until he came back and we hung out talking for 2-3 hours (I also polished/reset the valves and showed him how to clean/oil and reuse the gaskets).
It turned out that we used to visit his parent's farm when I was very young to purchase and cut our X-Mas tree (some 16 years prior).
I told my father about it and he replied "your'e shitting me - really?".
Many of my family "relationships" have always been a mystery to me in that when little I thought that my great and great/great grandmothers on one side were sisters.
