Some of my statements in previous posts are in error. I have, since they were posted two years ago, obtained the comprehensive collection, "The Collected Writings of Louis Riel," in five volumes; George F. G. Stanley, General Editor, 1985, The Univ. Alberta Press.
Volume 4, edited by Glen Campbell (Univ. Alberta), is devoted to the poetry composed by Riel, some 160 of them included in the volume. Some not included are in relatives handwriting, are drafts, etc.

Neither "Chanson de Louis Riel" (Joe has kindly provided a midi of the tune used by M. Jeannotte) nor "Quand je partis ma chè Henriette" are by Riel, they are the work of Metis poet-singers.
