One night in the Black Lion, Richmond, Yorks, Mick Sheehan was singing 'The Rybuck Shearer'. At each chorus I was baffled by 'and I'll never ???sore??? to take another blow' so murmured a sound something like I was hearing. Whispering to my neighbour "never what?" he nor the next knew either and half the company were making guessing noises.
Without knowing, one would never work out 'I'll never open Sorbies'
