Sign, sign, everywhere a sign

If you are of a certain age – i.e., a bit ancient like yours truly – you will recall a hit song from 1971 from a one-hit wonder Canadian rock group that called themselves the Five Man Electrical Band. For those of you not familiar with the song, it was called “Signs” and it was a protest song, something that occurred with regularity back in those days. The song reached No. 3 in the United States, and topped the charts in Australia.
