The concerts were to have run Jan. 30, Feb. 6 and Feb. 13. No reason was given for the change. The presentation of the in-progress musical was to have been produced by Tom Hulce and directed by Michael Mayer.

The musical, according to the official Joe's Pub website, concerns the story of "Duane and Molly's road trip in a beat-up Chevy truck, from the southernmost tip of Florida to the northernmost corner of New York, with plenty of unexpected detours along the way."

The musical features a book by Keith Bunin and music and lyrics by Patty Griffin. Griffin has released five albums, including "Impossible Dream and 1000 Kisses." The Dixie Chicks recorded her songs "Truth #2" and "Top of the World." Playwright Bunin has penned The Credeaux Canvas, The World Over, The Principality of Sorrows and The King of Clocks. Playwrights Horizons will present Bunin's The Busy World Is Hushed this spring.
