25 Minutes to Go

"25 Minutes to Go" is a song by Shel Silverstein, from his 1962 album "Inside Folk Songs".
Lyrics.
The song is literally "gallows humor", as it is sung by a man awaiting his own execution by hanging. Each verse consists of two lines, of which the first line is anything from humorous to poignant, and the second line is a minute-by-minute countdown.
The song is similar in concept to Silverstein's children's song "Boa Constrictor": It presents the point of view of someone who is experiencing a calamity in "real time," composing and singing as the events unfold, with a fatal conclusion. "Boa Constrictor", like "25 Minutes to Go", appeared on Silverstein's 1962 album "Inside Folk Songs".
