Visconti is the family name of two important Italian noble dynasties of the Middle Ages. There are two distinct Visconti families: The first one (chronologically) in the Republic of Pisa in the mid twelfth century who achieved prominence first in Pisa, then in Sardinia where they became rulers of Gallura. The second rose to power in Milan, where they ruled from 1277 to 1447 and where several collateral branches still exist.

The Visconti of Gallura used a cock as their symbol (Gallura meaning 'land of cocks'), whereas the later Visconti of Milan used a biscione (a great serpent) swallowing a Saracen, or, according to another version, on the contrary giving life to a child. This symbol is still closely connected with Milan.

Any link between the two families in Pisa-Gallura and Milan has yet to be proven.

The first Visconti of note in Pisa was Alberto, who bore the title patrician. Alberto's son, Eldizio, bore the titles patrician and consul from 1184 to 1185. It was Eldizio's sons, Lamberto and Ubaldo I, who brought the family to the height of its influence in Pisa and Sardinia. Both of them carried the title of patrician and each served a term as podestà.

David Bowie ( /ˈboʊ.i/ BOH-ee; born David Robert Jones on 8 January 1947) is an English musician, actor, record producer and arranger. A major figure for over four decades in the world of popular music, Bowie is widely regarded as an innovator, particularly for his work in the 1970s. He is known for his distinctive voice and the intellectual depth and eclecticism of his work.

Bowie first caught the eye and ear of the public in July 1969, when his song "Space Oddity" reached the top five of the UK Singles Chart. After a three-year period of experimentation he re-emerged in 1972 during the glam rock era with the flamboyant, androgynous alter ego Ziggy Stardust, spearheaded by the hit single "Starman" and the album The Rise and Fall of Ziggy Stardust and the Spiders from Mars. Bowie's impact at that time, as described by biographer David Buckley, "challenged the core belief of the rock music of its day" and "created perhaps the biggest cult in popular culture." The relatively short-lived Ziggy persona proved merely one facet of a career marked by continual reinvention, musical innovation and striking visual presentation.

Mary Hopkin (born 3 May 1950), credited on some recordings as Mary Visconti, is a Welsh folk singer best known for her 1968 UK number one single "Those Were The Days". She was one of the first musicians to sign to The Beatles' Apple label.

Hopkin was born in Pontardawe, Wales into a Welsh-speaking family; her father worked as a housing officer. She took weekly singing lessons as a child and began her musical career as a folk singer with a local group called the Selby Set and Mary. She released an EP of Welsh-language songs for a local record label called Cambrian, based in her home town, before signing to The Beatles' Apple Records. The model Twiggy saw her winning the British ITV television talent show, Opportunity Knocks and recommended her to Paul McCartney. She became one of the first artists to record on the Beatles' Apple record label.

Her debut single, "Those Were the Days", produced by McCartney, was released in the UK on 30 August 1968 (catalogue number APPLE 2). Despite competition from a well-established star, Sandie Shaw, who released her version of the same song as a single that same year, Hopkin's version became a number one hit on the UK Singles Chart, and reached Number 2 in the US Billboard Hot 100. It sold over a million and a half copies in the United States alone, and was awarded a gold disc by the R.I.A.A.. Global sales topped the eight million mark.
