Amplitudes for eta and eta'..--> pi../sup +/..pi../sup -/..gamma.., K/sub e//sub 4/, ..omega --> pi../sup +/..pi../sup -/..pi../sup 0/, and ..gamma --> pi../sup +/..pi../sup -/..pi../sup 0/ are constructed that respect the low-energy chiral-anomaly theorems but also have realistic vector-meson pole continuations to physical energies, respecting the well satisfied Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin relation. The amplitudes are compared to experiment, with good results, verifying the need for the current-algebra ''contact'' term.
