Using CLEO data collected from CESR e+e- collisions at the ψ(2S) resonance and nearby continuum at √s=3.67 GeV, we report the first significantly nonzero measurements of light vector-pseudoscalar hadron pair production (including ρπ, ωπ, ρη, and K*0K0̅ ) and the π+π-π0 final state, both from ψ(2S) decays and direct e+e- annihilation.
