the song cálice, by chico buarque and gilberto gil, was presented live for the first time at Phono73, a music festival in são paulo in 1973 sponsored by phonogram - the song was a protest against censorship conflict seen at the time, and ironically, when they began their performance the military turned-off their microphones, feeding the idea of censoring material.

the name cálice was given by chico and gilberto as a play-on-words, resembling the portuguese phrase 'cale-se', meaning shut up.
