“Broadsword”— Jethro Tull
“I see a dark sail on the horizon, set under a dark cloud that hides the sun...
Bring me my broadsword and clear understanding, bring me my Cross of Gold as a talisman. Get up to the roundhouse on the cliff top standing- take the women and children and bed them down.... Bring me my Broadsword....”
A Fighting Soldiers song with ancient reference.
