Useless info here, but if some of you didn't know.
I knew this before the Internet, but copied & pasted for accuracy.
The title, "25 or 6 to 4," refers to the time of day: 25 or 26 minutes before 4 a.m. Lamm was looking at a clock, trying to find the right time to complete a lyric, and the indecision between 25 and 26 minutes led to the unique title, according to a music magazine. 🙂
