There were still a few 78s around when I was a kid in the 60s.
Once, around 2005, I was showing a young driller’s helper on a reverse-circulation rig how to set up the rotary sampler, and told him to keep it turning somewhere between the speed of a 33 record and that of a 45. Total blank look.
It suxs getting old.
I used to run the sound board at my church. I brought in a turntable for one particular song. The teenagers gathered around. On of them said it was like an old timey CD player.
