I'm not sure whether this piece was composed by
Atahualpa Yupanqui (1908-1992) or by Oscar "Cacho"
Valles (1924-2003), but I think the music was composed
by A. Yupanqui and the poem was written by O. Valles.
However, this is a transcription of the version that
Yupanqui recorded on the 1rst of August 1967 for
EMI-Odeon (LDB-136).
