Irish folk-singer Tommy Makem, best known for his years with the Clancy Brothers -- and for his eponymous Manhattan pub -- will conclude his current stand at Irish Repertory Theatre on Oct. 14. The evening of Irish history and music, titled invasions and legacies, began Sept. 27. The piece, thanks to brisk ticket sales, was extended five days before it even started performances.

Makem's show promises to tell the story of the Irish people through "music, song and poetry." A solo artist for several years now, Makem came to prominence as a member of the Irish folksinging group, The Clancy Brothers. Appearances on "The Ed Sullivan Show" and connections to the mid-60s Greenwich Village folk scene enhanced the group's reputation in America. Makem sang and penned such standards as "Four Green Fields" and "Farewell to Carlingford."

Irish Rep artistic director Charlotte Moore stages the concert, which features a set by Klara Zieglerova and lighting by Jason A. Cina. Musicians Ron D'Adario and Bob Mastro will also be featured in the show, according to production spokespersons.

Following the Makem show, Irish Rep has on its season roster a mounting of Samuel Beckett's avant-tragicomedy, Endgame, a new musical, and the U.S. premiere of Sebastian Barry's Our Lady of Sligo.
