I think one needs a pretty fast modem connection to view it properly. I've never had any trouble with viewing things in YouTube; I think it's a reputable enough site, but then my computer knowledge is very limited.

Anyway, it's standard tuning.

I don't think 'Bonny Boy' is the same as 'The trees...' - not if it's the one that starts something like 'I once loved a boy and a bonny, bonny boy' as sung by Anne Briggs et al.
