Beggars Opera - Light Cavalry lyrics

Not many folk can understand The poor old grey-haired man They see his madness shining bright When it came to this (end??) He thinks of many years ago When all the battles raged While he was send to fight the foe (Oh how the years are aged??) Now all he has is memories of another age All wonder will you laugh at him when he set our (sage??) We see him walking through the pod The poor old grey-haired man He thinks of all those days gone by With the flag (????) Oh light cavalry Listen to his tales he tells of battles won and lost He was saved, his friends have paid the cost Not many folk can understand The poor old grey-haired man They see his madness shining bright When it came to this (end??) He thinks of many years ago When all the battles raged While he was send to fight the foe (Oh how the years are aged??) Oh light cavalry
