Although the single cover reads "LIBÉRATE!", the label on the A-side of the vinyl is entitled "Free Yourself" and the song (as on the album), is sung in English. On August 5, 2011, the Spanish label RAMA LAMA has issued all of its recordings from 1967-1972. For the very first time all of them are available on CD. The compilation album is entitled: "CANARIOS - TODAS SUS GRABACIONES (1967-1972)".- David Ispaster
