  We compute the four-point function of scalar operators in CFTs with weakly
broken higher spin symmetry at arbitrary 't Hooft coupling. We use the known
three-point functions in these theories, the Lorentzian OPE inversion formula
and crossing to fix the result up to the addition of three functions of the
cross ratios. These are given by contact Witten diagrams in AdS and manifest
non-analyticity of the OPE data in spin. We use Schwinger-Dyson equations to
show that such terms are absent in the large $N$ Chern-Simons matter theories.
The result is that the OPE data is analytic in spin up to $J=0$.
