The opening bass and drums are one of the all time best opening hooks. I've got to confess that I listened to this a number of times "way back when" and wondered what "25 or 6 to 4" was all about. Then Duh! - "twenty-five of twenty-six minutes to four in the morning." I've always been capable of abysmal stupidity at times.
