Questions 67 and 68

Questions 67 and 68 was Chicago's first single, written by Robert Lamm and sung mainly by Peter Cetera, with Lamm also on vocals. Lamm said in 2008 that it was about a girl he knew in those two years, with a hint of acid imagery and strong Beatles influence. It was one of two songs, with Does Anybody Really Know What Time It Is?, that he completed just before the band left Chicago for California.

James Pankow explained that his horn writing at the time was very harmonic, with no rests, so that the section played from the first bar like a big band. Released as a mono single in July 1969, it peaked at number 71. Edited for radio and reissued in September 1971 with I'm a Man on the B-side, it reached number 24. Cetera and Lamm recorded Japanese-language vocals for it in 1971 for a Japanese promotional single. Panic! at the Disco sampled it in Hallelujah.
