Ed Shaughnessy, 84, the jazz drummer who for nearly three decades anchored the rhythm section of Doc Severinsen's Tonight Show band died Friday of a heart attack at his home in Calabasas, outside Los Angeles, said family friend William Selditz.

Mr. Shaughnessy, a New Jersey native, began his jazz career as a teenager, playing with Billie Holiday, Benny Goodman, and Count Basie. He replaced Buddy Rich in Tommy Dorsey's band. In the mid-1950s, Mr. Shaughnessy became a staff musician at CBS.

From 1963 to 1992, he was a late-night-television fixture as part of the house band on Johnny Carson's show. - AP
