“David Drew, a music critic and musicologist who almost single-handedly rescued the work of Kurt Weill from neglect and promoted him to his present position as an important 20th-century composer, died on July 25 in London. … Mr. Drew, a lifelong champion of under-recognized 20th-century composers, took on the cause of Weill, regarded as little more than as an appendage to Bertolt Brecht, shortly after the composer’s death in 1950.”
