This song first appeared on the Chicago Transit Authority
album in 1969, but it wasn't released as a single until late 1970, long after their second album had been issued. This is because of "Make Me Smile
," part of a suite of songs on that second album that the record company edited down for single release. When it became a hit, they learned that by chopping down Chicago's songs a bit, they could find a home among the popular tunes on AM radio. "Does Anybody Really Know What Time It Is?," in shortened form, reached its peak of #7 the first week of 1971.
