As fans of Sarah Brightman probably already know, her vocalised
version of Watermark was released on her limited cd
The Harem Tour that can be bought only at the HAREM
concerts. I bought a copy at her concert in Prague, so here is
Sarah’s comment to the song from the cd booklet.

"WATERMARK is my vocalise version of a beautiful
instrumental by Enya. It was recorded for the TIMELESS Album* but
we never finished it after Enya and her record company (which was
also mine at the time) threatened me to put an injuction on my
album."
