I'll let Cetti answer this - it's his/her favourite question - having answered it about 4 times already, the first time for me and then for subsequent people. He/she will get to you eventually I'm sure. Go Cetti!!!!
Only 4! Just going out so this is the shortened version!
The music is called "The Lamb" by John Tavener. Feel free to take over, flirty - I won't mind - honest!!!!
Thanks but no thanks Cetti - you're the expert on this question! Just to add though (as Cetti was in a rush!) that the other well-known piece of music by John Tavener was 'Song for Athene' used at Princess Diana's funeral. Both available on the album 'Innocence'. Next please!!
