[Q]: 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.

[A]: Answer: 45


[Q]: Passage: Lord Jersey married Lady Sarah Sophia Fane, daughter of John Fane, 10th Earl of Westmorland, on 23 May 1804. She was the eldest grandchild and heiress of Robert Child, principal shareholder of the banking firm Child & Co. Lord Jersey added the surname Child to the Villiers surname by royal licence in 1819. Lady Jersey was one of the great hostesses of English society, a leader of the ton during the Regency era and the reign of George IV, and a patroness of Almack's. Lord Jersey was an ardent fox hunter and a breeder and trainer of horses, owning two Epsom Derby winners, in Mameluke (1827) and Bay Middleton (1836) as well as other notable thoroughbreds such as Glencoe. His wife's numerous love affairs did not trouble him: asked why he had never fought a duel to protect her honour, he replied that he could hardly fight every man in London.

[Q]: Passage: In 1975 his orchestral Fourth Sonata (written 1974–75) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (1977–81), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortège was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American première in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American première of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.
