"Autumn Leaves" - my dear departed brother used to have a special way of singing this.
"Wonderful World" - my Dad's favourite, played at his funeral. We sang it in choir last year, it took me weeks to sing without snivelling, but I concentrated on the music and not the words and finally got over it.
"The Folk who Live on the Hill" - Peggy Lee sings this so beautifully, and the verse ending "Baby and Joe who used to be Jack and Jill" always sets me off!
"Still Magic" by Peter Skellern - we play this in the car, my husband loves it and always pats me on the arm when this comes on, the words say it all.
"Moonlight Serenade" Glenn Miller - one of Mum's special tunes, and played at her funeral.
"Stop Right There" - Spice Girls - now for a happy tune, my granddaughters, now grown-up, used to sit on the back seat singing this one, complete with actions.
It has been lovely to read your special tunes, the song about the father was very moving, almost as bad as "The Living Years". Now I'm away to find the tissues!
