Question: Robert Anson Heinlein (; July 7, 1907 - May 8, 1988) was an American science fiction writer. Often called the "dean of science fiction writers", his sometimes controversial works continue to have an influential effect on the genre, and on modern culture more generally. Heinlein became one of the first American science fiction writers to break into mainstream magazines such as The Saturday Evening Post in the late 1940s. He was one of the best-selling science fiction novelists for many decades, and he, Isaac Asimov, and Arthur C. Clarke are often considered the "Big Three" of English-language science fiction authors.

Heinlein's experience in the U.S. Navy exerted a strong influence on his character and writing. He graduated from the U.S. Naval Academy in Annapolis, Maryland with the class of 1929 and went on to serve as an officer in the Navy. He was assigned to the new aircraft carrier USS Lexington in 1931, where he worked in radio communications, then in its earlier phases, with the carrier's aircraft. The captain of this carrier was Ernest J. King, who later served as the Chief of Naval Operations and Commander-in-Chief, U.S. Fleet during World War II. Heinlein was frequently interviewed during his later years by military historians who asked him about Captain King and his service as the commander of the U.S. Navy's first modern aircraft carrier.  Heinlein also served aboard the destroyer USS Roper in 1933 and 1934, reaching the rank of lieutenant. His brother, Lawrence Heinlein, served in the U.S. Army, the U.S. Air Force, and the Missouri National Guard, and he rose to the rank of major general in the National Guard.  In 1929, Heinlein married Elinor Curry of Kansas City in Los Angeles, and their marriage lasted about a year. His second marriage in 1932 to Leslyn MacDonald (1904-1981) lasted for 15 years. MacDonald was, according to the testimony of Heinlein's Navy buddy, Rear Admiral Cal Laning, "astonishingly intelligent, widely read, and extremely liberal, though a registered Republican," while Isaac Asimov later recalled that Heinlein was, at the time, "a flaming liberal".

Problem: The Electric Light Orchestra (ELO) are an English rock band formed in Birmingham in 1970, by songwriters/multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan. Their music is characterised by a fusion of Beatlesque pop, classical arrangements, and futuristic iconography. After Wood's departure in 1972, Lynne became the band's leader, arranging and producing every album while writing virtually all of their original material. For their initial tenure, Lynne, Bevan and keyboardist Richard Tandy were the group's only consistent members.

For the next six years, Harvest and Epic/Legacy reissued ELO's back catalogue. Included amongst the remastered album tracks were unreleased songs and outtakes, including two new singles. The first was "Surrender" which registered on the lower end of the UK Singles Chart at number 81, some 30 years after it was written in 1976. The other single was "Latitude 88 North".  On 9 August 2010, Eagle Rock Entertainment released Live - The Early Years in the UK as a DVD compilation that included Fusion - Live in London (1976) along with never before released live performances at Brunel University (1973) and on a German TV show Rockpalast (1974). The US had a slightly edited release on 24 August 2010. The Essential Electric Light Orchestra artwork was re-jigged to feature two different covers. The US and Australian releases shared one design, while the rest of the world featured the other for a new double album release in October 2011.  Mr. Blue Sky: The Very Best of Electric Light Orchestra was released on 8 October 2012. It is an album of new recordings of ELO's greatest hits by Lynne; along with a new song "Point of No Return", released to coincide with Lynne's second solo album release Long Wave. These new 2012 albums contained advertisement cards, announcing the re-release of expanded and remastered versions of both the 2001 album Zoom and Lynne's debut solo album Armchair Theatre, originally released in 1990. Both albums were re-released in April 2013 with various bonus tracks. Also released was the live album, Electric Light Orchestra Live, showcasing songs from the Zoom tour. All three releases also featured new studio recordings as bonus tracks.  Lynne and Tandy reunited again on 12 November 2013 to perform, under the name Jeff Lynne and Friends, "Livin' Thing" and "Mr Blue Sky" at the Children in Need Rocks concert at Hammersmith Eventim Apollo, London. The backing orchestra was the BBC Concert Orchestra, with Chereene Allen on lead violin.
