Well I recognise your name for some reason. Dads gone for a nanna nap after his medicinal guinness.  (Its 7pm here in Perth WA)
I will read him your reply when he gets up.  Allan McCrystal and my brother Mark Harrison used to knock around together until my family emigrated in 74.  Allan was a bit of trouble back then from the stories I've heard lol.  (Dear cousin Allan, when you inevitably find this post, it was meant it the most affectionate manner.  I did however hear about your mad skills intervening in a fight that broke out in the, ahem dole queue back in the day; and it turned out you were fighting another relative of mine haha.)
