Will someone please post the lyrics for the song Gunner Name of Bill.
The music was written by Michael Smith to a poem by Theodore Cogswell.
Do you have any information about its writer beyond what is on Wikipedia, HERE ?

When was it written? Does it have any temporal connnection with the Spanish Civil War 1936 - 1939?
It is performed by Jamie O'Reilly and Michael Smith on their Cd Pasiones: Songs of the Spanish Civil War
