Jim Croce sang about saving time in a bottle so that he could "spend it with you". Steve Miller sang about time "slippin, slippin, slippin into the future" and the things he'd like to do. Miller wanted to "fly like an eagle" to "feed the babies, shoe the children, and house the people.." all worthy causes in my opinion. These and numerous other songs about time express our awareness of time, even if you are "sitting on the dock of the bay, wastin time" as Otis Redding sang about. Incidentally Mr. Redding recorded this hit song in Dec 7, 1967, three days before his death in a plane crash outside Madison, Wisconsin according to what I've read. Indeed our time is so uncertain here.
