this may require a deeper research.
original album notes mentions D.R. (
Derechos Reservados - All Rights Reserved), meaning that it sure has authorial copyright but they don't knew at that time who is/are the composer(s). tracking composers at that time was difficult (now is easier with google), specially if the publishing company was located in foreign countries. when in doubt, most record companies displayed the famous D.R.; others done it just to avoid any royalties payment.
might help if we can know other performers (artists or groups) to expand this search.
