He moved from the cathedral to the collegiate church of St. Martin, also in Tours, where he became a subdeacon in 1465. Johannes Ockeghem was treasurer at that institution, and the two composers seem to have known each other well. Later in 1465 Busnois moved to Poitiers, where he not only became master of the choirboys but managed to attract a flood of talented singers from the entire region; by this time his reputation as singing teacher, scholar and composer seems to have spread widely. But he departed in 1466 just as suddenly as he came for no known reason, and the former master was given his old job back. He then moved to Burgundy.
