-- The

set for Sunday has been postponed, the city said Saturday.

The May 1 festival was put on hold due to the expected rainy weather, according to a statement from the city. Officials said a later date would be announced.

The annual spring celebration was scheduled to feature headliner Leon Russell, a veteran singer and songwriter. The scheduling change was made in coordination with Russell, city officials said.

An estimated 40,000 to 45,000 people flock to the city each year for the festival, which includes a range of artists, food vendors and other groups along Washington Street.
