NEW YORK (AP) _ Technical glitches forced the cancellation of two preview performances of the new Broadway musical ``Amour.''

Problems with the set interrupted the Saturday evening performance, causing a 15-minute delay, Bill Evans, a spokesman for the show, said Monday.

Parts of the scenery were returned to the set shop for modification, he added, resulting in the cancellation of the Tuesday evening performance and the Wednesday matinee.

``Amour,'' a fantasy about a man who can walk through walls, contains several special effects. The musical, which has a score by French composer Michel Legrand, stars Malcolm Gets and Melissa Errico and is directed by James Lapine. It is scheduled to open Oct. 20 at the Music Box Theatre.
