Ah Jerusalem, I'm another one who finds it difficult to get all of the words out, as you say it is usually at funerals but a very wonderful song and I believe the lyrics were composed by William Blake in Sussex?
and the music was composed by Hubert Parry in Rustington.
Tunes for me are, in particular order,
Morning Glory by Tim Buckley or This Mortal Coil
Hurt by Johnny Cash
Nothing Compares 2U By Sinead or Prince
Sometimes it Snows In April by Prince and The Revolution (at my funeral please.)
Imagine by John Lennon
