Just to mention that I may well have visited the roller rink in the very late Forties and that for sure I did do so from time to time in the Fifties - sometimes there were very long queues outside, you could use your own skates or hire them - sometimes the borrowed ones were pigeon toed, the noise was very great and of course there was music which in the circumstances had to be pretty loud too. The prices I cant now remember but would have had to be quite cheap. Of course it was quite good fun to go there.
