The name Dorman keeps cropping up in this thread and it took me back to 1969 when I was at Mawson, the oldest contiuously used research station in the Antarctic. The main power generator in the powerhouse at that time was a "Dorman" and I wonder at the connection.
To keep the mucis aspect of the thread alive I really liked Vin's songs (and their introductions) and his singing but his tin whistle was top hole! JUst after I first heard The Young Tin Whistle Pest the '75 National in Sydney brought a young tin whistler out of the woodwork. He knew most of the tunes and those he didn't know he'd pick up after the first time through. His style was a mirror image of Vin's and we found out he came from Middlesbrough. Ian Stewart got married soon after and became a maths teacher; I haven't heard a peep from or about him since. A pity 'coz he was a nice bloke and an asset to any session.
