Livre d'Or

The Ardgour songbook is a thing; feel free to email me about that [it's a not entirely public thing]. Most of the recorder playing I do these days is for dancing, usually the Round (so mostly Playford, but a pile of other things), if that sounds like fun I could put you in touch with the person who organises the band. There are some fun recorder duets (I nearly did some for my A-level). I'm not aware of many specific voice+recorder arrangements.
