Susan sings her own story. Therefore the sweet assurance.

Coming from a small Scottish town

A might frumpish, ungarnished

Nervous sense of humour showing.

But then a pause 

Entire audience still, eager

Wondering.

And Susan's voice exploded

Like incoming beams from Heaven.

With all of a Heart's

Emotion, thanks  and Joy.

New Star had arrived.

Audience roared their approval.

Simon simply smiled.
