Marjorie Bligh The Musical, an original work by Launceston playwright Stella Kent and composer Karlin Love, will be further developed in London.
The musical attracted the attention of The Other Palace, an off West End theatre that is one of seven London theatres owned by Andrew Lloyd Webber.
The Other Palace has a development program aimed at discovering and nurturing works that make exciting, new, bold musical theatre. It was impressed by the unusual subject and larger-than-life heroine who was rumoured to be the inspiration behind Barry Humphries' Dame Edna Everage, Ms Kent said.
"We'd love to see the musical given a fully staged production here," she said.
The musical tells the story of iconic Devonport housewife Marjorie Bligh, famed for her sometimes quirky domestic advice.
