Lyrics:

A pretty tune comparing a crisis in a relationship to the momentary nature of swimming swans.Should it be over before it's begun
Drifting away in the warmth of the sun
Turning away round the curve in the stream
Then disappearing through tunnels of green
Swans on the canal
Drifting along like a song
Taking their time in the sun
Swans on the canal
Glide through reflections so still
Slowly they pass by me
But should it be over before its begun
Drifting away in the warmth of the sun
Turning away round the curve of the stream
Then disappearing through tunnels of green
