A simple model based on meson annihilation is proposed to explain low mass production of lepton pairs for both hadron and neutrino beams. Resonances, such as the rho and omega, are naturally taken into account and are shown to give rise to a large but unexpected contribution at very low pair masses. Numerical results are given together with comparisons to data. For the most part, the normalizations are taken from other experimental data. -
