In June 1941, Letritia Kandle appeared as a guest performer with the Chicago Plectrophonic Orchestra under the direction of Jack Lundin. The orchestra consisted of mandolins, banjos, acoustic and electric guitars, accordions, string basses, and various percussion instruments. Her performance with the group took place at Chicago’s Goodman Theater and began with Lundin’s arrangement of John Philip Sousa’s Washington Post March. The performance also included several arrangements by Kandle, including “Pagan Love Song,” “Moon of Manakoora,” “Hawaiian War Chant,” and “To You Sweetheart Aloha.” After Lundin died in 1943, Kandle became the director of the forty-nine-piece ensemble. In their 1944 annual concert at the Goodman Theater, most of the program included works arranged by Letritia. While later concerts featured Kandle in one or two solos, by 1946 her principle role was the conductor of the ensemble. In 1955, she married Walter Lay, one of the string bass players for the ensemble.
