  The warped conformal symmetries have been found in the covariant phase space
of a set of non-trivial diffeomorphism near the Kerr black hole horizon. In
this paper, we consider the retarded Green's function and the absorption
probability for the scalar and higher spin perturbations on a generic
non-extreme Kerr black hole background, and perform their holographic
calculations in terms of the warped CFT. This provide further evidence on the
conjecture that the warped CFT is relevant to the microstate description of the
Kerr black hole.
