A Pirate's Morph: Soul To Hurt

A tuppence, old chap, grant this whiskied SOUL Whose mind wears weak and heart grows SOUR Take not from thee for what surely is OURS To quench a lad's thirst at this haunted HOUR And drown from our swarthy souls the HURT Morph verse is utlizing the last word of each line and morphing it. Removing one letter from the previous last word and adding an additional letter to complete the subsequent word. EX: SOUL - remove the L and add an R to create SOUR. SOUR - Remove The S in SOUR and add it to the end of OUR. OURS - Remove the S and add and an H to the beginning of OUR. HOUR - Remove the O and add a T to create the word HURT. So on and so forth.
