Richard Hayman went from harmonica player to music arranger to pops conductor, all without any formal musical training. Along the way, he made arranged the music for Hollywood movies, earned a star on the Hollywood Walk of Fame, did arrangements for the Boston Pops for more than 50 years, and founded and ran the St. Louis Symphony Orchestra’s pops concerts for three decades, while drawing on a seemingly endless collection of sequined jackets. Mr. Hayman died Wednesday (Feb. 5, 2014) in New York City, of natural causes. He was 93, and had recently entered hospice care.
