If we're also doing true stories which just happen to be funny then I'll sling this one in:
now, please note this is not an 'Irish joke', as they are generally lovely people and don't deserve it. However...many years back, when I was in a band doing the pubs and clubs of Northern England we once got a gig at a Catholic club in Leeds, sort of in the Hunslet area. I looked it up on the street map and it seemed easy to find but, pre (by a long time) sat-nav the inevitable happened and we got lost. However, all was not lost as we were near at a long queue standing at a bus stop, and someone was bound to know where it was. And they did. a very nice chap who just happened to Irish -perfect for knowing where the Catholic club would be!
"Ah, you need to go back up to the red light at the crossroads. Then turn left and go down the hill about half a mile and you'll see the church- you can't miss it. Have you got that? back to the red... no no, to the GREEN light, turn left etc"
There are some things you just can't make up, though I confess I used it as a joke for years in the band and I've heard it told by others - but it was me it really happened to!
