Composer-lyricist Leslie Bricusse has exited the developing tuner version of “Sleepless in Seattle.”

Bricusse (“Stop the World — I Want to Get Off,” “Victor/Victoria”) and producers parted ways over the creative direction of the show’s tunes. “We’re looking for a bit of a more contemporary sound,” said producer David Shor.

Bricusse had penned 18 songs for the musical’s score.

Book writer Jeff Arch, who co-wrote the 1993 TriStar pic, and director Joel Zwick (“My Big Fat Greek Wedding”) remain attached to “Sleepless.”

Book is now complete, and Shor is hoping to have a new composer-lyricist team onboard in the next few weeks.

Proposed sked for the tuner, which has an anticipated capitalization of $12 million-$15 million, remains aggressive. A preem was originally intended for spring 2010, but that timeline looks likely to be pushed back at least until fall of next year.
