The rest of the company, including Malcolm Gets as a randy leprechaun and Jonathan Freeman as Finian, continues in the revised concert staging, at Irish Rep's home on West 22nd Street.
Performances were to run to May 30, but audience interest in the classic by Yip Harburg, Fred Saidy and Burton Lane prompted an extension to July 11. Errico played Sharon since previews began April 6.
Finian's Rainbow, as unlikely a musical hit as ever there was, opened April 15. Irish Rep artistic director Charlotte Moore adapted the 1947 Yip Harburg-Fred Saidy-Burton Lane musical satire for a benefit concert in 2003, and a version of that script is heard in this run, also directed by Moore.
The company also includes David Staller as the Narrator, Mark Aldrich, Jonathan Hadley, Eric Jackson, Jayne Lynch, Kimberly Dawn Neumann, John Sloman (as Sen. Rawkins), Joacquin Stevens and Terri White (Barnum). Designers include James Morgan (set), Mary Jo Dondlinger (lighting) and David Toser (costume).
Tickets for Finian's Rainbow are $40-$45. Performances play Wednesday-Sunday at Irish Rep, 132 W. 22nd Street (between Sixth and Seventh avenue).
