In 1973, me and 2 mates went for a "cultural" holiday in Lloret de mar. (Believe that and I have some magic beans I can sell you)
One morning, about 5am, we were returning from an educational trip to the various hostelries in the town, when we bumped into 5 other lads who had also been visiting the cultural highlights.
It must be pointed out that we were singing traditional songs robustly at the time (eg, "we'll drink a drink a drink...."), and the lads asked if we were English, which we confirmed. One of the lads then said "We just love Manchester City!"
It turned out that they were all members of the Oslo branch of the Supporters Club.
We returned to our hotel, with our guests, and fortunately the bar was still open, so we had a long discussion with them, with several drinks, before bidding them adieu.
