Fran Warren, whose 1947 recording of "A Sunday Kind of Love" was one of the classic hits of the big band era, has died.

Alan Eichler, a spokesman for the singer-actress, said Tuesday that Warren died March 4 of natural causes at her home in Brookfield, Conn. She was 87.

Warren's career spanned more than 50 years with hits that included the Tony Martin duet "I Said My Pajamas (and Put On My Prayers)," the Lisa Kirk duet "Dearie" and "It's Anybody's Heart." Her films roles included "Abbott and Costello Meet Captain Kidd."

She frequently appeared and performed on the talk shows of Johnny Carson, Mike Douglas, Merv Griffin and Steve Allen.

Warren is survived by two daughters, a son-in-law and two nieces.
