I recently took a muscian friend to a session where he heard The Band played Waltzing Mathilda for the first time and was moved to tears.
Keith Marsden used to write a lot of songs from his own experience or stories other people told him. One of the ones I find particularly poignant is "St Aubin sur Mer" a description he was given of the D Day landings from a bloke he was talking to in a pub. A song of bitter grief but a story that should be told I feel.
