  We discuss the meromorphic continuation of certain hypergeometric integrals
modeled on the Selberg integral, including the 3-point and 4-point functions of
BPZ's minimal models of 2D CFT as described by Felder and Silvotti and Dotsenko
and Fateev (the ``Coulomb gas formalism''). This is accomplished via a
geometric analysis of the singularities of the integrands. In the case that the
integrand is symmetric (as in the Selberg integral itself) or, more generally,
what we call ``DF-symmetric,'' we show that a number of apparent singularities
are removable, as required for the construction of the minimal models via these
methods.
