Harping on: musical prodigy's midlife crisis stage show

Rita Costanzi was an exceptionally gifted harpist from childhood. "Shame," sniffed friends of her father, the great American violinist Francis Tursi.

A Score to Settle is the story of the life that unfolded behind this most physical and misunderstood of instruments, moulded with Broadway director Arthur Masella into an award-winning solo show that settles into the Butterfly Club from Wednesday until Sunday.

"It's a midlife crisis story," the New York actor-virtuoso says. "There's a fine line between myself and my character: she's very loveable, deluded, over the top. And she's funny."
