From the Tommy liner notes by Brian Cady:
It was released as the B-side of the single "See Me Feel Me" which constituted the first 4'00 of the Overture.
A cover version by The Assembled Multitude reached #16 in the U.S. in June 1970. It has also been covered by Henry Mancini and Liberace among many others.
Didn't come home
His unborn child,
Will never know him
Believe him missing
With a number of men
To see him again.
