I have improved the language and section structure, but some portions need more work. Jargon should be explaine, for example laymen may not understand the portion "was released on 45 rpm record in 1960, with "Doce Doce" as B-side" (What is a 45 rpm record? What is a B-side?). Also, the section "Personal life" is confusing because it begs the question of why Fred's wife was briefly married to someone else (A previous marriage? Divorce?). :)
