In my earlier piece on Some Corner of a Foreign Field I forgot to mention that one of the poems is The Volunteer by Robert Service. 
I also have a powerful collection of Service’s wartime poems set to music by Country Joe McDonald, called War, War, War. It came out in 1971, was briefly reissued on CD in 1995, and is well worth getting hold of. The most gut-wrenching piece is the last: The March of the Dead (and yes, I know that this is about the Boer War, not the Great War – but the sentiment is timeless).
Speaking of Country Joe, check out the new song by the Country Joe Band, Cakewalk to Baghdad. It’s a cheerful little ditty in the spirit of the immortal I-Feel-Like-I’m-Fixin’-to-Die Rag ; and as they sing, it’s Easy to cakewalk in … not so easy to cakewalk out.
