They weren't "cardboard" records. They were plastic glued onto the cardboard box, so they were actually very thin vinyl with a cardboard backing.
I seem to remember having a few. The Monkees maybe? They sounded like shit and wore out very quickly.

I have no recollection whatsoever of these recordings but surely some of the slightly older members do?
I booked my first Jazz cruise yesterday. The old Jazz Cruise is now called "McBride's World At Sea 2026": https://mcbridesworldatsea.com/, I only booked it because i had a flight credit expiring and McBride posted a discount code on Facebook, XMAS, that was good for $1,500/person off of a Conceirge Class room.
Now I just have to hope that Boston doesn't get socked with a blizzard on January 20th, when my flight leaves.
BTW - if anyone sees this and decides to go, feel free to list me as your referral.
