Tant Que Vivray
(Long Shall I Live)
French words by Clément Marot, music by Claudin de Sermisy / arr., with English words, by Patrick M. Liebergen
Alfred Choral Designs
Excellent 3-part writing, right on the mark for young men and women. Teach the song in English before introducing the optional French text (an IPA pronunciation guide is included). When your students are ready to sing a cappella, consider eliminating the piano accompaniment---it works either way.
