A theorem of G.Wilson and the first author asserts that G acts transitively the Calogero-Moser spaces C_n for all n. We generalize this theorem in two ways: first, we prove that the action of G on C_n is doubly transitive, meaning that G acts transitively on the configuration space of (ordered) pairs of points in C_n; second, we prove that the diagonal action of G on the product of (any number of) copies of C_n is transitive provided the corresponding n's are pairwise distinct.
