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

Here is what I think is the original song, "Campfire's Burning",
which is often sung in the UK!

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