Busnois was at the siege of Neuss in Germany in 1475, and survived (or missed) the disastrous Battle of Nancy in 1477 at which Charles was killed and Burgundian expansion was ended forthwith and forever.
Amongst the more well-known versions of the song are the 3-voice version by Busnois, its reworking for 6 voices by Alexander Agricola, a 3-part instrumental version possibly by Josquin, and a 3-voice version by Heinrich Isaac.
