In 1465 he moved from the cathedral to the collegiate church of St. Martin, also in Tours, where he became a subdeacon. Johannes Ockeghem was treasurer there, and the two composers seem to have known each other well. Later in 1465 Busnois moved to Poitiers, where he not only became "maîtrise" (master of the choirboys), but managed to get lots of good singers from the region. By this time he was famous as a singing teacher and composer. However he left the job for some reason in 1466 and then moved to Burgundy.
