A tribute to children's public television pioneer Fred Rogers will include an effort to get people everywhere to wear a sweater on what would have been his 80th birthday.

March 20th is being promoted as "Sweater Day" to honor Rogers, who died of cancer five years ago. A sweater was his trademark garb on "Mister Rogers' Neighborhood."

David Newell, who played speedy deliveryman Mr. McFeely on the show, appears in a YouTube video that touts the event.

"Sweater Day" is the capstone to a six-day celebration planned by Family Communications Inc. of Pittsburgh. Rogers created the company to produce his show.
