  The Virasoro field associated to b,c ghost systems with arbitrary integer
spin lambda on an n-sheeted branched covering of the Riemann sphere is
deformed. This leads to reducible but indecomposable representations, if the
new Virasoro field acts on the space of states, enlarged by taking the tensor
product over the different sheets of the surface. For lambda=1, proven LCFT
structures are made explicit through this deformation. In the other cases, the
existence of Jordan cells is ruled out in favour of a novel kind of
indecomposable representations.
