We show that the method of 'MHV rules' for computing on-shell amplitudes in Yang-Mills, follows from a change of variables in the Yang-Mills Lagrangian. We use this insight to derive extra completion rules that provide the contributions that are otherwise missing when these rules are applied in non-supersymmetric theories.
