I know two of them and sadly one of them has passed away now. He was a younger brother of a good friend of mine at the time. There were four of them as I can recall and they all went to Sir Christopher Wren and were in the year below me, which would've been SLF's and Wisey's year. SLF and Wisey weren't anywhere near the vicinity of Hammersmith Park on that night. Not that the incident should be anything to be proud of, but teenagers get up to high jinx regardless of the era. This just happened to be a high profile one which some tried to achieve notoriety by claiming to be there when they weren't even there which I find strange.
