 During the recording sessions Olivencia found out that Santiago was still under contract with his previous label and had Simón Pérez re–record Santiago's vocals.Three tracks from those sessions with Santiago's vocals, ""Que Dichoso Es"", ""La Pela"" & ""Del Montón"", later appeared on Santiago's compilation ""15 Éxitos De Marvin Santiago"" released by TH Records in 1984.Famous arranger and producer Jorge Millet knew Santiago well and their friendship could be traced back to the late 1960s when they met while both lived in the city of Chicago.
