“Mr. Anderson was the voice of Lucky the Leprechaun, a mischievous cartoon redhead in a green coat, from 1963 to 1992. “Frosted Lucky Charms,” he’d sing, “they’re magically delicious.”” Full obituary at The NY Times. Arthur was 93 (clearly outliving anyone who ever ate Lucky Charms).

Rest in Peace, Arthur!
