@Granny23 : You've kindled a memory, with 'gutties'!
A member of the RAF Band in which I served, in Cyprus in the 50s, was a lovely gentle soul from the west of Scotland somewhere - he wasn't always easy to understand, I have to say. One day, he pointed at something in my tent and said "Wha's gu''ies are yuck?' (He glottal-stopped the 't's in gutties).
We questioned him for some time, but to this day I'm not certain if it was 'Whose plimsolls are the ones with the stains?' or '... are full of stones?' that he was asking!
Ah well, his euphonium playing spoke volumes...
