Copenhagen ( /ˈkoʊpənheɪɡən/ or /ˈkoʊpənhɑːɡən/; Danish: København pronounced [kʰøb̥m̩ˈhɑʊ̯ˀn] ( listen), Latin: Hafnia) is the capital of Denmark and its most populous city, with an urban population of 1,213,822 (as of 1 January 2012 (2012 -01-01)^[update]) and a metropolitan population of 1,935,746 (as of 1 April 2012 (2012 -04-01)^[update]). With the completion of the transnational Øresund Bridge in 2000, Copenhagen has become the centre of the increasingly integrating Øresund Region. Within this region, Copenhagen and the Swedish city of Malmö are growing into a combined metropolitan area. Copenhagen is situated on the islands of Zealand and Amager.

First documented in the 11th century, Copenhagen became the capital of Denmark in the beginning of the 15th century. During the 17th century, under the reign of Christian IV, it became a significant regional centre.

Copenhagen is a major regional centre of culture, business, media, and science, as indicated by several international surveys and rankings (see International rankings below). Life science, information technology and shipping are important sectors, and research & development plays a major role in the city's economy. Its strategic location and excellent infrastructure, with the largest airport in Scandinavia,Kastrup, located 14 minutes by train from the city centre, have made it a regional hub and a popular location for regional headquarters and conventions.

Thomas Andrew Lehrer (born April 9, 1928) is an American singer-songwriter, satirist, pianist, and mathematician. He has lectured on mathematics and musical theater. Lehrer is best known for the pithy, humorous songs he recorded in the 1950s and 1960s.

His work often parodies popular song forms, though Lehrer usually creates original melodies when doing so. A notable exception is his song "The Elements", where he sets the names of the chemical elements to the tune of the "Major-General's Song" from Gilbert and Sullivan's Pirates of Penzance. Lehrer's earlier work typically dealt with non-topical subject matter and was noted for its black humor, seen in songs such as "Poisoning Pigeons in the Park". In the 1960s, he produced a number of songs dealing with social and political issues of the day, particularly when he wrote for the U.S. version of the television show That Was The Week That Was.

In the early 1970s, he retired from public performances to devote his time to teaching mathematics and music theatre at the University of California, Santa Cruz. He did two additional performances in 1998 at a London gala show celebrating the career of impresario Cameron Mackintosh.

Robert Earl Keen, Junior (born January 11, 1956) is an American Texas country music and folk guitarist and singer-songwriter from the southern state of Texas. He is popular with fans of various musical genres including traditional country, alternative country, folk, Americana, and college radio. Keen currently resides in Kerrville, Texas, and maintains a ranch in Medina, Texas.

Growing up in Houston, Texas, Keen was interested in music, sports, movies and writing. Keen graduated from Sharpstown High School in 1974.

Keen attended Texas A&M University, where he majored in English. Disappointed in the College Station music scene, he began playing guitar and learned to read and write music, basing his style on folk, country, blues and rock roots. In 1974 he rented a house from landlord Jack Boyett, where his neighbor was a then-unknown Lyle Lovett. The two became fast friends and performed together on the front porch many evenings. This eventually grew into inspiration for a song entitled "The Front Porch Song", which both would add to their repertoire.

A leading figure in the hospitality and food & beverage industries, Robert Earl is the founder and CEO of Planet Hollywood International, Inc and the chairman of the Planet Hollywood Resort & Casino in Las Vegas, Nevada.

A lifetime entrepreneur, Earl founded President Entertainment in 1977, a company specializing in theme restaurants that grew from a modest start-up to a company valued at more than $100 million when he agreed to sell the company to Pleasurama in 1998. Earl was invited by Pleasurama to join its executive team and orchestrated the acquisition of Hard Rock Café. During his five-year tenure as the CEO of Hard Rock Café, Earl oversaw the expansion of the brand from its initial seven units to 22 units, and dramatically increased the Company’s profitability. This growth was a direct result of aggressive marketing and non-stop positive press capitalizing on Earl’s vision to use the allure of Celebrity and creative events to earn Hard Rock Café a mystique that separated it from its competition.
