Question: Information:  - A ballad is a form of verse, often a narrative set to music. Ballads derive from the medieval French "chanson balladée" or "ballade", which were originally "danced songs". Ballads were particularly characteristic of the popular poetry and song of the British Isles from the later medieval period until the 19th century. They were widely used across Europe, and later in the Americas, Australia and North Africa. Ballads are 13 lines with an ABABBCBC form, consisting of couplets (two lines) of rhymed verse, each of 14 syllables.  - Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek  ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound."  - Jesus Christ Superstar is a 1970 rock opera with music by Andrew Lloyd Webber and lyrics by Tim Rice. The musical started as a rock opera concept album before its Broadway debut in 1971. The musical is sung-through, with no spoken dialogue.

It highlights political and interpersonal struggles between Judas Iscariot and Jesus that are not present in the Bible narratives.  - Slowhand is a 1977 album by Eric Clapton.

Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly.  - "Lay Down Sally" is a song performed by Eric Clapton, and written by Clapton, Marcella Detroit (as Marcy Levy, the diminutive form of her birth name), and George Terry.

In 1986, Cleveland was chosen as the hall of fame's permanent home.

Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - Marcella Detroit (born Marcella Levy, June 21, 1952) is an American soprano vocalist (perhaps best known for her backup singing on many Top 20 Billboard hits), guitarist, and songwriter.
