The Song COOKHOUSE, which is strongly associated with the Spanish Civil War, seems to derive its verse tune from HAPPY LAND although the chorus tune comes from another 19th Century song KIND WORDS CAN NEVER DIE. Q gives the link above to the thread detailing his well researched information which links the two songs in World War One: The chorus was printed in F. T. Nettleingham, 1917, "Tommy's Tunes," no. 53, p. 58, "Old Soldiers Never Die," tune given as "Kind Words Can Never Die." A parody

COOKHOUSE as performed by Pete Seeger & The Almanac Singers      

From the Album: Canciones De Las Brigadas Internacionales -
Songs Of The International Brigade.

There is an old cookhouse not far away
Where we get sweet damn all, three times a day.
Ham and eggs we never see,damn all sugar in our tea,
and we are gradually,fading away.

Old soldiers never die,
Never die, never die,
Old soldiers never die
They just fade away.
