There's no mention there of him playing Northumbrian pipes but I have seen a TV programme many years back (dating from the mid 60s, I think), of the Corries singing to pipes and I'm sure it was Roy playing them. In fact, that was the first time I ever saw the pipes live, although I had heard Colin Ross on the Folk Song Cellar radio programme and that's when I decided I had to get some. It didn't happen until 1972, but Roy was part of my inspiration and determination.
