The wall-crossing formula for Donaldson invariants of smooth, simply connected four manifolds with b+=1 is shown to be a topological invariant of the manifold for reducible connections with two or fewer singular points. The explicit formulas derived agree with those of Ellingsrud and Gottische and Friedman and Qin for algebraic manifolds.
