Jane New Dorsey, dancer, warbler and the widow of bandleader Tommy Dorsey, died of natural causes Sunday in Bay Harbor, Fla. She was 79.

Born Jane New in Dublin, Ga., she graduated from high school in her hometown before moving to New York to attend the Albiene School of the Theater, then joined the chorus of a Ziegfeld Follies revival on Broadway that starred Milton Berle. The production boasted almost a two-year run, during which time she became a specialty dancer and understudy to the lead chantoosie. Dorsey also performed as a chorus hoofer at the Copacabana.

She married Dorsey in 1948 and appeared alongside her husband in the Sam Goldwyn pic “A Song Is Born,” which starred Danny Kaye.

She later owned and maintained the Tommy Dorsey Orchestra with the original music library.

She is survived by a son and a daughter; a son-in-law and a daughter-in-law; five grandchildren; and two cousins.

Graveside services will be held 1 p.m. Saturday in Kensico Cemetery, Valhalla, N.Y., where she will be buried next to her husband.

Contributions can be sent to the Bascom Palmer Eye Institute.
