Luxembourg (ⁱ/ˈlʌksəmbɜrɡ/ LUKS-əm-burg), officially the Grand Duchy of Luxembourg (Luxembourgish: Groussherzogtum Lëtzebuerg, French: Grand-Duché de Luxembourg, German: Großherzogtum Luxemburg, Dutch: Groothertogdom Luxemburg), is a landlocked country in western Europe, bordered by Belgium, France, and Germany. It has two principal regions: the Oesling in the North as part of the Ardennes massif, and the Gutland ("good country") in the south. Luxembourg has a population of over half a million people in an area of approximately 2,586 square kilometres (998 sq mi). A representative democracy with a constitutional monarch, it is ruled by a grand duke. It is now the world's only remaining sovereign grand duchy. The country has a highly developed economy, with the world's highest GDP (nominal) per capita according to the IMF. Its historic and strategic importance dates back to its founding as a Roman era fortress site and Frankish count's castle site in the Early Middle Ages. It was an important bastion along the Spanish Road when Spain was the principal European power influencing the whole western hemisphere and beyond in the 16th–17th centuries.

Sean Taro Ono Lennon (Japanese name Tarō Ono (小野 太郎, Ono Tarō^?); born October 9, 1975) is an American singer, songwriter, musician, guitarist and actor of English, Japanese and Irish descent. He is the only child of John Lennon and Yoko Ono and the younger half-brother of Julian Lennon. His godfather is Sir Elton John.

Sean Lennon was born in New York City on October 9, 1975, his father's 35th birthday. Julian Lennon is his half-brother and Kyoko Chan Cox is his half-sister. After Sean's birth, John became a house husband, doting on his young son until his murder in 1980. Sean attended kindergarten in Tokyo, and was also educated at the exclusive private boarding school Institut Le Rosey in Rolle, Switzerland, and earlier at New York's private Ethical Culture Fieldston School and Dalton School. He later attended Columbia University, though for only three semesters before dropping out to focus on his music career.

His parents did not force him into the life of a musician: they intentionally hid their musical lives from their son. His debut into the music world came at the age of five, reciting a story on his mother's 1981 album Season of Glass. From childhood into his teen years, Sean continued to collaborate with his mother, contributing vocals and receiving production credit on her solo albums It's Alright (I See Rainbows), Starpeace and Onobox. At 16 Sean co-wrote the song "All I Ever Wanted" with Lenny Kravitz for his 1991 album Mama Said. By 1995 Sean had formed the band IMA (with Sam Koppelman and Timo Ellis) to play alongside his mother on her album Rising. Sean also made appearances in film, featured in the cast of Michael Jackson's 1988 Moonwalker and portraying a teenager experiencing visions of various M. C. Escher paintings in Sony's 1990 promotional short-film Infinite Escher.
