No I am 27 I know what vinyl is and that they were available at 331/3, 45 and 72 I think, as my brothers and I used to play the records at 72 to make people sound like the chipmonks or slow them down to distort the song, but I never really thought until now about what the LP stood for. Did you have an 8track too?
Thank you for putting me in my place and letting me know.
I also know what LP is on my VHS recorder the thing that came out before a DVD!!
