The light scattering properties of superconducting (Tc=3.8 K) heavily boron doped nanocrystalline diamond has been investigated by Raman spectroscopy at several wavelengths using visible excitations. Fano type interference of the zone-center phonon line and the electronic continuum was identified at all wavelengths. Fano lineshapes with a significant asymmetry were fitted. The anomalous wavelength dependence of the Raman scattering amplitude of the phonon transitions and its small value were confirmed..
