The reason is that I have just been listening to a CD of Frankie Laine, really listening, this lyric is lovely, wish I could post the tune to go with it, but I can't find it.

There must be a reason for raindrops to fall.
There must be a reason why mountains are tall.
And why are the stars in the sky?
There must be a reason why.

There must be a reason for rivers to flow.
For beautiful trees and flowers to grow.
And why have the birds wings to fly?
There must be a reason why.

The changes from season to season,
The dawning that brings the new day.
These wonders mist all have a reason,
It was intended that way.

There must be a reason for falling in love,
It must have been planned up in Heaven above.
And why are we so much in love, you and I?
There must be a reason why.

The changes from season to season,
The dawning that brings the new day.
These wonders mist all have a reason,
It was intended that way.

There must be a reason for falling in love,
It must have been planned up in Heaven above.
And why are we so much in love, you and I?
There must be a reason why.
There must be a reason why.
There must be a reason for raindrops to fall.
There must be a reason why mountains are tall.
And why are the stars in the sky?
There must be a reason why.

There must be a reason for rivers to flow.
For beautiful trees and flowers to grow.
And why have the birds wings to fly?
There must be a reason why.

The changes from season to season,
The dawning that brings the new day.
These wonders mist all have a reason,
It was intended that way.

There must be a reason for falling in love,
It must have been planned up in Heaven above.
And why are we so much in love, you and I?
There must be a reason why.

The changes from season to season,
The dawning that brings the new day.
These wonders mist all have a reason,
It was intended that way.

There must be a reason for falling in love,
It must have been planned up in Heaven above.
And why are we so much in love, you and I?
There must be a reason why.
There must be a reason why.
