We present here the current Nançay observing program gathering the pulsar french community around the radio follow-up of X- and gamma-ray pulsars for the building of a complete multi-wavelength sample. The goal of this project is double : 1) provide strong constraints on the physics and emission mechanisms of pulsars , 2) guarantee the success of pulsar harvest at high energy by providing good and contemporaneous ephemerides for folding the few gamma and X-ray photons . The community is well involved in the last generation of gamma-ray and X-ray detectors and the availability of the NRT and its dedicated backend BON represents a very good opportunity for acquiring the necessary and complementary radio data.
