This Note resurrects some isospin relations involving I = 3/2 and I = 1/2 amplitudes that shed light on relative strengths among cross sections for neutrino production of single pions in scattering from quasi-free nucleons. The relations enable a number of quantitative statements to be made about neutrino cross sections for CC single pion production; these are developed and briefly discussed.
