  We study the relation between the partition function of refined SU(N) and
SO(2N) Chern-Simons on the 3-sphere and the universal Chern-Simons partition
function in the sense of Mkrtchyan and Veselov. We find a four-parameter
generalization of the integral representation of universal Chern-Simons that
includes refined SU(N) and SO(2N) Chern-Simons for special values of
parameters. The large N expansion of the integral representation of refined
SU(N) Chern-Simons explicitly shows the replacement of the virtual Euler
characteristic of the moduli space of complex curves with a refined Euler
characteristic related to the radius deformed c=1 string free energy.
