Seeing as it was a discussion of Victoria's music that started this copyright discussion, some of you might like to know that the editor Jon Dixon, who's near London, has for about 15 years steadily been making superb editions, including now the complete works of Byrd and Victoria, and he's working on Lassus and Palestrina too. Plus lots and lots of early English Catholic music by the likes of Tallis, Sheppard, Ludford, Mundy etc. My choir in the UK has used several of his editions, they are competitively priced and often include several works by one composer in one score. He can print your editions to order, at any pitch you need them to be. Choirs that regularly turn to him for editions include Westminster Cathedral Choir, Gabrieli Consort etc. He doesn't seem to have a dedicated website that I can find, but there is plenty of info in this link:

Here is his article on Victoria:

I hope this is of help.

This was all I was able to find, he doesn't seem to have a website or a visible email. If you phone him direct from the USA, it's 011-44-208-643-4995. His name's Jon Dixon
