Indeed. But then, looking back at WAV's list...

INSTRUMENTS OF (OR CLOSELY ASSOCIATED WITH) ENGLAND

Northumbrian Bagpipes (bellows blown), Leicestershire Bagpipes (mouth blown); English Concertina, Anglo Concertina, Duet Concertina (and important developments to – if not inventions of – other keyboards, such as piano and organ, have also occurred in England); Dital Harp/Harp-Lute, English Cittern; English Flageolet, Penny Whistle, Recorder/English Flute

...they're all chordal instruments apart from the whistles. Apparently 'English traditional' means what he says it does, except when it doesn't.

But we already know it's impossible to argue with this guy. A reminder for anyone still tempted...

WAV: [the recorder]'s certainly been played in this land for a long time; and, at the Rothbury TRADITIONAL Music Festival, there is a competition for whistles AND recorders.

Volgadon: I see that the Rothbury TRADITIONAL Music Festival also has a competition for highland bagpipes

WAV: Volgadon - I do like the Scottish Highland Pipes but disagree with Rothbury, ENGLAND, on that one.

It's all evidence for WAV's argument - unless the evidence doesn't support him, in which case he's right and the evidence is wrong.
