"25 or 6 to 4", also written as "Twenty-Five or Six to Four", is a song written by the American musician Robert Lamm, one of the founding members of the rock/jazz fusion band Chicago. It was recorded for their second album, Chicago in 1970, with Peter Cetera on lead vocals. The song was edited and released as a single in June that year, climbing to number 4 on the U.S. Billboard Hot 100 chart and number seven on the UK Singles Chart. This recording features an electric guitar solo using a wah-wah pedal by Chicago guitarist Terry Kath, and has been included in numerous Chicago compilation albums. <br /> <br />An updated version of "25 or 6 to 4" was recorded for the 1986 album Chicago 18 with James Pankow listed as co-writer. With the new band member Jason Scheff on lead vocals, the single reached number 48 on the U.S. chart. <br />Lyrics <br />Speculation that the song's lyrics are drug related has been largely dismissed. Lamm himself says that the title is "just a reference to the time of day" and that "the song is about writing a song. It's not mystical." The title serves as an answer to a concurrent Chicago song: "Does Anybody Really Know What Time It Is?" The answer is 25 or 26 minutes to 4 o'clock.
