Jazzman William (Billy) Moore Jr.

William (Billy) Moore Jr., who replaced Sy Oliver as the arranger in the Jimmy Lunceford band in 1939 and crafted such jazz masterpieces as “Belgium Stomp,” “What’s Your Story Morning Glory” and “Monotony in Four Flats,” died Tuesday in Copenhagen.

He was 71 and had been battling lung cancer.

After leaving Lunceford after only one year, Moore wrote for Charlie Barnet, Jan Savitt and Tommy Dorsey and did the charts for Barnet’s ever-popular “Skyliner.” Barnet told Times jazz critic Leonard Feather on Wednesday that Moore was a “wonderful arranger, and I’m sorry he didn’t get the recognition he deserved.”

Moore left the United States more than 30 years ago for Europe after many disappointing experiences with the racial attitudes then prevalent in America.

After settling in Europe, he composed for French bands and toured as music director and pianist for the Peters Sisters, a singing group. He later toured Europe with the Delta Rhythm Boys before settling in Copenhagen.
