The Cornwall Songwriters new show 'Unsung Heroes - The Lost Gardeners of Heligan' is a tale about the gardeners that go away to the first world war, It has fine songs on this theme and there is a CD and a book of the entire script, which would be a useful resource. Fine songs such as Jon Heslop's 'Poor Murdered Men' Roger Bryant and Mike O'Connor's 'Foreign Fields' Tony Truscott's 'Where The Sun Meets The Shadows and Lucy Burrow's 'Battlefield Tree ' are all worth a listen.
I have copies of the CD available for sale, please pm me for details
Cheers, Lucy
