Crook Sludge - Brass Jaw

One man's crook full of sludge is another man's crock full of just-watered John Innes compost on a beautiful, hot, sunny morning!!!!!!! (Thus spake the Mole)

Almost impossible to do this one in the absence of a musical instrument which has gathered a lot of 'gunk' in one of its bends/ crooks!

In case you wonder who Brass Jaw are!
