  We describe a class of the singular solutions to the multicomponent analogs
of the Lam{\'e} equation, arising as equations of motion of the elliptic
Calogero--Moser systems of particles carrying spin 1/2. At special value of the
coupling constant we propose the ansatz which allows one to get meromorphic
solutions with two arbitrary parameters. They are quantized upon the
requirement of the regularity of the wave function on the hyperplanes at which
particles meet and imposing periodic boundary conditions. We find also the
extra integrals of motion for three-particle systems which commute with the
Hamiltonian for arbitrary values of the coupling constant.
