“ On the 22nd of February 1569 he was sworn in as a member of the Chapel Royal, but he does not seem to have left Lincoln immediately. In the Chapel Royal he shared with Tallis the honorary post of organist, and on the 22nd of January 1575 the two composers obtained a licence for twenty-one years from Elizabeth to print music and music-paper, a monopoly which does not seem to have been at all remunerative. In 1575 Byrd and Tallis published a collection of Latin motets for five and six voices, printed by Thomas Vautrollier. In 1578 Byrd and his family were living at Harlington, Middlesex. ”
