Many thanks,especially to GARY T .. yes I know but look at the info you teased out for me. Thanks for the link Stewie, it is spot on.. It's great to be able to pick your brains for Bluegrass music , which I have loved ever since the early sixties when I came across it as part of the American Folk Revival. That sparked off an enormous re-awakening of interest among younger people here too, in traditional Irish music (But you are probably aware of that anyway). Perhaps , from time to time I can call on your valuable assistance again??
