Guest from sanity: I have been at funerals where they have played the music of the deceased: quite a surreal feeling about it!
My father died on Christmas Day 2010, and we had "Crossing the Bar" sung by Craig, Morgan and Robson from their CD "Stranded" at the end of the church service: my father had been in the Navy, so the nautical imagery was very appropriate, and the singing was haunting, albeit recorded.
