I think it'd be a great idea if, as you say it works on the Irish model where ability and understanding of the music are the key attributes a competitor requires for entry. However, WAV is typically evasive when it comes to who could enter, and that raises suspicions - not unreasonable.

Anyhow, I'm off to practice my English tunes on my Irish bouzouki.
