Hi, My Mum found this out, from Alan Titchmarsh, for my daughter who, when 10 yrs. old, loved it so much that she wanted to walk down the aisle to it !
It is called 'Morning Light' (by N.Webb / G. Carmichael ) and is recorded on their album 'Easy-GOING Guitars Atmos-29'.
The address and phone no. on the cover is;
Atmosphere Music LTD
65 Maltings Place,
Bagleys Lane,
London SW6 3AR
017 371 5888.
Hope you can get hold of it !
