I've just listened to Highland Laddie and I think there is too much ornamentation for Colin. It's a more Scottish style but I think they are Northumbrian pipes.
Roy Williamson, of the Corries, played Geordie pipes but would he have been in that place at that time?
Was it recorded in London or in the US given the recording co. name?
And if so, might it have been an American piper?
Grit Laskin has pipes too and has been singing for a long time.
Maybe Julia can find out.
