We focus primarily on radiative meson decays which involve one pseudoscalar. The agreement with experiment for non-rare decays is surprisingly good and requires very few parameters, namely the coupling constants $g_{πqq}$ and $g_{ρqq}$ and some mixing angles. This agreement extends to some three-body decays that are dominated by pion pairs in a P-wave state.21 pages, Revtex, one figureHigh Energy Physics - Phenomenologytext
