God love him if he was still in nappies when the Pope visited Ireland - he was 11 at the time.
Are you doubting his facts because you think he was in nappies at the time? I once had to write an essay on Moses leading the Hebrew slaves out of Egypt, but I didn't actually witness it, in or out of nappies.
He was 11 he still hardly knew the facts of life, so you are saying that he saw all these young lovers doing their stuff while visiting the Pope. If they are people buying his rubbish book's to read then fair play to him for making easy money.
