The Hamelin Tragedy

My heart sunk while I was standing On the pavements of Hamelin town Grieving along with its mothers' souls The disappearance of their children Like a hungry dragon Mount Kooppenberg Opened its mouth and swallowed them, It was the brutal revenge of a strange piper That made him lead the kids to the mount It was the pied piper with a magical tune in his pipe Led the entire rats to river Weser and drowned When Life in Hamelin became miserable And the exploding rat population sickening Denial of the deal amount made him desperate And deciding to avenge played another tune Under the spell of which all the children gathered And followed the pied piper to the mountain It is confusing, who was treacherous in the tale The strange pied piper who avoided the rats Or the mayor who denied the deal amount Or the people of Hamelin who lost their children?
