  Let $M$ be a singular hyperkaehler variety, obtained as a moduli space of
stable holomorphic bundles on a compact hyperkaehler manifold
(alg-geom/9307008). Consider $M$ as a complex variety in one of the complex
structures induced by the hyperkaehler structure. We show that normalization of
$M$ is smooth, hyperkaehler and does not depend on the choice of induced
complex structure.
