It's all about grass being greener: I always used to think that centre-free records (except ex-jukebox) were very cool, because they came from foreign lands. Like French singles which had no centres and always always had a picture cover (usually printed on a sort of grained waxy paper), and so had their own coolness. I currently have a small collection of Spanish 'ye-ye' singles which, when in good condition, are startlingly bright and colourful, and make me very happy as long as I can pick them up for between 0 and 3 euros. Here are two that I have. The first one gives a fair idea of how rockers in 1966 looked in Spain; the lead track is "The Pop Gypsy", just to cover all the bases. The second EP probably needs no translation. There is something glorious about the vinyl single.
I've got loads of 45's with the centre punched out as back in the 60's I bought a portable record player on the beach in Riccione and used to take it in the car with me. It would only play records with centres missing. Somewhere I've got the gismo that goes in the centre.
I remember those portable record players that only played 45's. My brother had one that he and gf would take with them on outings. I really wanted one of those.
