The phrase above is the first line of the Rolling Stones "Before they make me run" song lyrics. Here's the complete verse:
Worked the bars and sideshows along the twilight zone / Only a crowd can make you feel so alone / And it really hit home
I never was able to find out what's the meaning of this phrase, none of the possible translations for it in Portuguese makes any sense.
Also: in some sites the lyrics appears with the expression "Worked in bars" in place of "Worked the bars", but I have no clue about which of them should be considered the "correct" one.
