Passage: The station became WQXL in 1962 after the station was sold to the Belk Broadcasting Company. The WOIC call sign resurfaced that same year on 1320 AM (now WISW). WQXL originally aired a Big Band format, which eventually gave way to a Top 40 format by the end of the decade. However it was handicapped with a daytime-only signal and was unsuccessful in competing against format rivals 1230 WNOK and 1400 WCOS, which each had full-time signals. Probably its most notable personality was Mackie "Cactus" Quave who had worked at 560 WIS (now WVOC) and had a successful kids TV show on NBC Network affiliate Channel 10 WIS-TV. WQXL switched to country music in the summer of 1966, but again was bested by rival 620 WCAY (now WGCV). In 1973, the station switched to religious programming and eventually adopted a Contemporary Christian format.

Passage: Maurice had to continue the war against the Persians. In 586 his troops defeated them at the Battle of Solachon south of Dara. In 588, a mutiny by unpaid Byzantine troops against their new commander, Priscus, seemed to offer the Sassanids a chance for a breakthrough, but the mutineers themselves repulsed the ensuing Persian offensive. Later in the year they secured a major victory before Martyropolis. The Sassanid commander, Maruzas, was killed, several of the Persian leaders were captured along with 3,000 other prisoners, and only a thousand men survived to reach refuge at Nisibis. The Byzantines secured much booty, including the Persian battle standards, and sent them, along with Maruzas' head, to Maurice in Constantinople. In 590 two Parthian brothers, Vistahm and Vinduyih, overthrew King Hormizd IV and made the latter's son, Prince Khosrau II, the new King. The former Persian commander-in-chief, Bahram Chobin, who had rebelled against Hormizd IV, claimed the throne for himself and defeated Khosrau. Khosrau and the two Parthians fled to the Byzantine court. Although the Senate unanimously advised against it, Maurice helped Khosrau regain his throne with an army of 35,000 men. In 591 the combined Byzantine-Persian army under generals John Mystacon and Narses defeated Bahram Chobin's forces near Ganzak at the Battle of Blarathon. The victory was decisive; Maurice finally brought the war to a successful conclusion with the re-accession of Khosrau.

Passage: Elvestrand was born in Østre Gausdal. His father was an organist at Østre Gausdal Church and Follebu Church, and he allowed Magne to play there in 1927. Elvestrand studied organ under Arild Sandvold and Fartein Valen, who dedicated his opus 33 to him, and studied theory, harmony, and counterpoint under Gustav Fredrik Lange and Per Steenberg. At the age of 18 he was made cathedral organist at Oslo Cathedral while Eyvind Alnæs was ill and then continued in this function after Alnæs's death until Sandvold was appointed to the position. During the commemoration of the 200th anniversary of Bach's death in 1950, Elvestrand played all of Bach's works at Grefsen Church, where he was organist from 1940 to 1967. He debuted as a pianist in 1956, and he performed his first full harpsichord concert in Copenhagen in 1962. Elvestrand served as the organist at Trinity Church in Oslo from 1967 to 1984. As a teacher, he worked at the Oslo Conservatory of Music from 1942 to 1954 and from 1966 to 1973, at the Norwegian Academy of Music from 1973 to 1984, and at the Huseby public school for the blind from 1952 to 1975. He retired in 1981. Elvestrand's solo album was nominated for the 1977 Spelleman Awards in the classical/contemporary music category, but the award was won by Grex Vocalis. Elvestrand died in Germany.
