Disney musical 'Little Mermaid' bobs along at Olney

When last seen on Broadway in 2009, Disney's $15 million musical "The Little Mermaid" was quietly sinking under the waves after a run of less than two years. A planned major national tour of Francesca Zambello's high-gloss production never materialized (this was before she became artistic director of the Washington National Opera), so regional theaters have begun to take it on.
