Production of events with multihadronic and leptonic final states has been measured in e(+)e(-) collisions at centre-of-mass mass energies significantly above the Z(0) mass, using the OPAL detector at LEP. A substantial production rate of radiative Z(0) gamma events was observed, as expected, together with events with less energetic initial-state photons, The cross-sections and leptonic forward-backward asymmetries were measured and compared with Standard Model expectations, In a model-independent fit to the Z(0) lineshape, the hadronic cross-section and lepton asymmetries presented here provide constraints on the size of the gamma Z(0)-interference term which are complementary to those afforded by LEP data accumulated at the Z(0) resonance.
