  We calculate connected correlators in Gaussian orthogonal, unitary and
symplectic random matrix ensembles by the replica method in the 1/N-expansion.
We obtain averaged one-point Green's functions up to the next-to-leading order
O(1/N) and wide two-level correlators up to the first nontrivial order O(1/N^2)
and wide three-level correlators up to the first nontrivial order $O(1/N^4)$ by
carefully treating fluctuations in saddle-point evaluation.
