Yep, I remember & used each & every one of them. I still have my 45's with the adapters & a record player that still works. When one of my Grandson's was about 8 (now 27) & we were sewing together, I ask him if he wanted to listen to some of my old songs. He was excite & when I pulled out my 45"s, he said "Gee grandma, I've never seen CD's that big before". Boy did I laugh. He was impressed not only with the songs on the 45's, but also the 78's I still have. He loved watching the arm go up to let another record play & the are return to play another song. I still have the 8track tapes & a player for them too. Don't figure I have to mention my age & some things I hoard. LOL
