"Signs" is a song by the Canadian rock group Five Man Electrical Band. It was written by Les Emmerson and popularized the relatively unknown band, who recorded it for their second album, Good-byes and Butterflies in 1970. "Signs" was originally released that year as the B-side to the relatively unsuccessful single "Hello Melinda Goodbye" (#55 Canada). Re-released in 1971 as the A-side, "Signs" reached No. 4 in Canada and No. 3 on the US Billboard Hot 100 chart. Billboard ranked it as the No. 24 song for 1971. It became a gold record.
