The date and place of his death also vary in sources. Orovio's English edition says 1961. This is definitely incorrect, because there are at least three recording session whose dates are later in the 1960s: in 1962/3 in Miami; in 1967/8 in New York, issued on Gema 3070 "Viva Portabales"; and, above all, in October 1970 in Puerto Rico, just a few days before his death (issued Gema 3086 "Sones cubanos: Guillermo Portabales con Los Guaracheros de Oriente"). This simple refutation throws doubt upon Orovio's other data, and has led to a general acceptance of Cristobal Díaz's version of 25 October 1970.
