If it is a Christian funeral, LOTS of songs from the Sacred Harp (Denson or Cooper) would be nice, especially "All is Well" (Denson, 122) "China" (Denson, 163) "Christian's Farewell" (Denson, 347) or "Parting Hand" (Denson, 64)- but those are just some of my favorites-! It would be better if you had about 100 howling singers, and put the bereaved in the center of the square, but a quartet could do OK.

There's also "Sweet Beulah Land" (AKA "Beulah Land") which I heard recently sung by a tenor-alto duo. It was shivery.
