Triumphant sound resonates again from a tiny church that survived the attacks of Sept. 11.

The booming sound of St. Paul's pipe organ broke the silence after being forced out of commission eight years ago.

The 200-year-old Manhattan church was the only structure left standing amid the fallen towers at ground zero-- shielded by a large sycamore tree.

Large amounts of soot and ash from the disaster clogged the church's organ pipes preventing them to play.

Now the church has cleaned nearly half of the 1,700 pipes for the organ's Easter Sunday debut.

"These pipes were cleaned with a bottle brush, paint brush and a vacuum cleaner," explained organ technician Larry Trupiano.

During the aftermath of the attacks, the church opened its doors to rescue workers for food and a place to rest.
