Our church choir sings this. Here's what I remember of it.

Keep Your Lamps

Part 1:
Keep your lamps trimmed and burning, [x3]
The time is drawing nigh.


Part 2:
Children, don't get weary, [x3] The time is drawing nigh.

If I find my sheet music before someone else posts more, if there is more to the song I'll post that, too.
