@richardbrand ”oops”
l was wondering if the World was turned upside down?
The way you worded it, it looked like you were implying l had an alias, and was in fact suspected of being “Faustuss”
Yes you are right about the number of grooves = 2
So many people get wound up trying to convert 33 revolutions per minute multiplied by the number on minutes a record will play. Still can be a good quiz question that catches out the uninitiated.
Congratulations for being the only one to work it out in writing.
l believe you are in Australia? I must ask you, do you see the Moon upside down?
