  In a recent paper, D. Harlow, J. Maltz, and E. Witten showed that a
particular proposal for the timelike Liouville three-point function, originally
due to Al. Zamolodchikov and to I. Kostov and V. Petkova, can actually be
computed by the original Liouville path integral evaluated on a new integration
cycle. Here, we discuss a Coulomb gas computation of the timelike three-point
function and show that an analytic extension of the Selberg type integral
formulas involved reproduces the same expression, including the adequate
normalization. A notable difference with the spacelike calculation is pointed
out.
