We have previously analysed the chiral predictions for the decay KL -> pi0 gamma e+ e- and discussed how experimental measurements of this process can help our undertanding of chiral theories and of CP tests. Motivated by the possibility that the analogous muonic process may soon be measureable, we extend this calculation to the decay KL -> pi0 gamma mu+ mu-. Branching ratios and differential branching ratios are calculated and presented. Measurements of these will help shed some light on the puzzles in our understanding of the chiral loop effects which were raised by the rate for KL -> pi0 gamma gamma.
