Dennis Greene | Sha Na Na founder, 66

Dennis Greene, 66, a founding member of the retro-rock/doo-wop group Sha Na Na who later became a movie studio executive and law professor, has died.

Mr. Greene's nephew, Edward Robinson, said his uncle died Saturday in Columbus, Ohio, after a brief illness.

Mr. Greene performed with Sha Na Na at Woodstock in 1969 and with the group in the 1978 movie Grease.

Robinson said Thursday that the New York native left the group in 1984 to study law and later worked as a Columbia Pictures vice president.

He said Mr. Greene appreciated the opportunities that arose from his music career, but law was his passion.

Mr. Greene began teaching law at the University of Dayton in 2001. - AP
