A manger or trough is a feeder of carved stone, wood, or metal construction used to hold food for animals (as in a stable). Mangers are mostly used in livestock raising. They are also used to feed wild animals, e.g., in nature reserves. The word comes from the French manger (meaning "to eat"), from Latin manducare (meaning "to chew").^{[citation needed]}

A manger is also a Christian symbol, associated with nativity scenes where Mary, forced by necessity to stay in a stable instead of an inn, placed the baby Jesus in a manger. (Luke 2:7). This is commonly misinterpreted as the manger being the stable.^{[citation needed]}

The model F142 Freeland hog trough is fairly typical of modern manufactured troughs; it is fabricated of 14-gauge galvanized sheet steel, 26 inches (66 cm) long, 14 inches (36 cm) wide and 6 inches (15 cm) deep, with a nominal capacity of 2.5 US gallons (9.5 l; 2.1 imp gal). Prior to the Second World War, virtually all hog troughs were homemade. Confinement feedlots typically use automated feeders, sold as wasting less feed and requiring less labor.

Susan Magdalane Boyle (born 1 April 1961) is a Scottish singer who came to international public attention when she appeared as a contestant on the TV programme Britain's Got Talent on 11 April 2009, singing "I Dreamed a Dream" from Les Misérables. Her first album was released in November 2009 and debuted as the number one best-selling album on charts around the globe.

Global interest in Boyle was triggered by the contrast between her powerful mezzo-soprano voice and her plain appearance on stage. The juxtaposition of the audience's first impression of her, with the standing ovation she received during and after her performance, led to an international media and Internet response. Within nine days of the audition, videos of Boyle—from the show, various interviews and her 1999 rendition of "Cry Me a River"—had been watched over 100 million times. Her audition video has been viewed on the internet several hundred million times. Despite the sustained media interest she later finished in second place in the final of the show behind dance troupe Diversity.

Henry John Deutschendorf, Jr. (December 31, 1943 – October 12, 1997), known professionally as John Denver, was an American singer/songwriter, activist, and humanitarian. After traveling and living in numerous locations while growing up in his military family, Denver began his music career in folk music groups in the late 1960s. His greatest commercial success was as a solo singer. Throughout his life Denver recorded and released approximately 300 songs, about 200 of which he composed. He performed primarily with an acoustic guitar and sang about his joy in nature, his enthusiasm for music, and relationship trials. Denver's music appeared on a variety of charts including country & western, the Billboard Hot 100, and adult contemporary, in all earning him 12 gold and 4 platinum albums with his signature songs "Sunshine on My Shoulders", "Take Me Home, Country Roads", "Leaving on a Jet Plane", "Rocky Mountain High", "Annie's Song", and "Calypso".

Denver further starred in films and several notable television specials in the 1970s and 1980s. In the following decades he continued to record, but also focused on calling attention to environmental issues, lent his vocal support to space exploration, and testified in front of Congress to protest censorship in music. He is known for his love of the state of Colorado, which he sang about numerous times. He lived in Aspen, Colorado, for much of his life, and influenced the governor to name him Poet Laureate of the state in 1974. The Colorado state legislature also adopted "Rocky Mountain High" as one of its state songs in 2007. He was an avid pilot, and died while flying his personal aircraft at the age of 53. Denver was one of the most popular acoustic artists of the 1970s.
