Composer John Williams has won practically every award possible in his long and distinguished career — Oscars, Emmys, Grammys, even the Kennedy Center Honor and the American Film Institute’s Life Achievement Award. So Broadcast Music Inc. (BMI), one of the nation’s leading performing-rights societies — which had already given him its top honor in 1999 — gave him an even higher honor by naming a new award after him. It was a particularly star-studded evening, as I tried to convey in this Variety story about the society’s annual Film, TV and Visual Media Awards in Beverly Hills.
