TOLEDO, Ohio (AP) — Jon Hendricks, the pioneering jazz singer and lyricist who with the trio Lambert, Hendricks & Ross popularized the "vocalese" singing style in which words were added to instrumental songs, has died. He was 96. His daughter, Aria Hendricks, confirmed his death to the New York Times. She said he died Wednesday at a New York City hospital. Hendricks found fame in the 1950s and '60s teaming with Dave Lambert and Annie Ross.
