Songs appropriate for children to sing at funerals?

[20wkbaby]

Any ideas of songs appropriate for children to sing at a funeral (of their great-grandmother in this case). Preferably that would already be familiar to them as some are not old enough to read quickly on sight.

Something not too morbid please?

All things bright and beautiful is a popular choice.

The children range from 6 to 11 so the younger ones probably couldn't follow the words easily of a song they were not familiar with. It will be at a crematorium but hymns are not necessarily out.

Just wondered if someone could think laterally and come up with a children's song that had some additional meaning relevant to a funeral. I am thinking about bedtime songs maybe...

Thanks StitchingMoss - All Things Bright and Beautiful has been suggested but rejected for some reason.

Morning has broken is lovely. I went to a funeral once and I cannot for my life sing its awful they put on All things bright and beautiful and I was the only one singing but I couldn't stop as that would have been worse!

Just made myself cry looking at the lyrics of lullabies and thinking of them being sung at a funeral. Especially as my grandmother whose funeral it is lost her own mother at 2 months old.
