Arranging, conducting and orchestral credits include Joaquín Prieto, Chucho Ferrer, Enrique Neri, Magallanes, Mario Patrón, Ángel "Pocho" Gatti, José Sabre Marroquín, Jean Poll, and Chucho Altamirano.
Artist's name José José appears on cover, but on label as José-José (with hyphen). The hyphenated form seems to have been dropped in the mid-1970s.
An orthographic note: On track B2, the writing of the name "L. de LLano" (on the container, but not on the label) is somewhat unusual. Note the letter LL in upper case. In checking my Larousse, it states LL is the 14th letter of the Spanish alphabet, and Larousse illustrates the correct usage of upper/lower case Ll for the upper case form. It's interesting to see variations in the usage of the special Spanish letters Ll (also Ch).
