  We consider the Jack--Laurent symmetric functions for special values of
parameters p_0=n+k^{-1}m, where k is not rational and m and n are natural
numbers. In general, the coefficients of such functions may have poles at these
values of p_0. The action of the corresponding algebra of quantum
Calogero-Moser integrals D(k,p_0) on the space of Laurent symmetric functions
defines the decomposition into generalised eigenspaces. We construct a basis in
each generalised eigenspace as certain linear combinations of the Jack--Laurent
symmetric functions, which are regular at p_0=n+k^{-1}m, and describe the
action of D(k,p_0) in these eigenspaces.
