25 or 6 to4 12/9/19

In 1970, the second single from Chicago's second album became one of the "Great Songs of the '70s"--but not without some controversy.

Some people believed that the title was a drug reference. In fact, several countries banned the song because of this. But according to Chicago's Robert Lamm, the title was about staying up all night trying to write a song. It was all in how you read it, phrased it, and sang it.

So actually, "25 or 6 to 4" was the time the song was written: 25 or (2)6 to 4(am)! The song went to #2 on the Hot 100 in Canada... and #4 in the U.S. TRIVIA: The original name of the group (and their self-titled first album) was Chicago Transit Authority... which didn't go over well with the real CTA. To avoid a lawsuit, the name of the group was shortened.

TRIVIA #2: The first release from the second L.P. was "Make Me Smile."
