We study a one-dimensional, two band model with short range electron-electron repulsions (onsite U and nearest-neighbour V terms) and electron-phonon coupling. We show that there is a region of U,V and band filling in which singlet superconductivity fluctuations are dominant. This region is absent without electron-phonon interactions and includes large values of U,V.
