OK – I found the recording, and it's not quite as I remembered it – easier in fact. Allan plays it with a simple "Dum-Ching" rhythm, and NOT as posted by Amos - "in a style similar to but slower than the famous riff in "La Bamba".

Flower In The Snow (From the Album "Lines" – 1988)

Allan Taylor

Capo 1st Fret

(D)    (A)
It was just a (D)moment, (A)    a moment of (D)passion (G)
Like a mountain (D)stream (G)crystalline and (Bm)clean
Tumbling and (D)crashing (A)
It was something (D)special (A)   few will ever (D)know (G)
Something out of (D)line (G)standing out of (Bm)time
A flower in the (D)snow (A)
(D)   (A)

He was just a wanderer on his way to nowhere
Like a bird in flight passing in the night
He didn't have a care
And she came to him in darkness, gave it all away
All the years of waiting, shyly hesitating
She stayed till day

(Chorus)

But the wanderer left her, travelled on his way
Whistling a tune for the man in the moon
Far away
She lit a candle, left it in her window
Let the light burn 'cause lovers never learn
How to let go

(Chorus) When it was just a moment….
