Fire's Burning
(source: "Jubilee Songbook", Girl Guides of Canada, 1971.)
(to the tune of "London's Burning"; can be sung as a 4-part round)

Fire's burning, fire's burning
Draw nearer, draw nearer
In the gloaming, in the gloaming
Come sing and be merry

Here is what I think is the original song, "Campfire's Burning", which is often sung in the UK. Thanks to Vicky White for sending it in.

(source: "Girl Guide Songbook, Vol. 2", Girl Guides Association, 1984.)

Camp fire's burning, camp fire's burning
Draw nearer, draw nearer,
In the glowing, in the glowing
Come sing and be merry
