Question: Who founded the chain of music-themed restaurants whose first establishment opened in the birthplace of the queen who agreed to turn the United Provinces into a protectorate of England?

full_context: Document 1: Dutch Republic: In 1582 the United Provinces invited Francis, Duke of Anjou to lead them; but after a failed attempt to take Antwerp in 1583, the duke left the Netherlands again. After the assassination of William of Orange (10 July 1584), both Henry III of France and Elizabeth I of England declined the offer of sovereignty. However, the latter agreed to turn the United Provinces into a protectorate of England (Treaty of Nonsuch, 1585), and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648.
Document 2: Southampton: Southampton has two large live music venues, the Mayflower Theatre (formerly the Gaumont Theatre) and the Guildhall. The Guildhall has seen concerts from a wide range of popular artists including Pink Floyd, David Bowie, Delirious?, Manic Street Preachers, The Killers, The Kaiser Chiefs, Amy Winehouse, Lostprophets, The Midnight Beast, Modestep, and All Time Low. It also hosts classical concerts presented by the Bournemouth Symphony Orchestra, City of Southampton Orchestra, Southampton Concert Orchestra, Southampton Philharmonic Choir and Southampton Choral Society.
Document 3: Hard Rock Cafe: The chain began to expand worldwide in 1982 with locations in (among others) Toronto, Los Angeles, San Francisco, Chicago, Paris, and Berlin. Hard Rock Cafe locations in the United States vary from smaller, more tourist driven markets (Biloxi, Pigeon Forge, Key West, etc.) to large metropolises (Houston, Philadelphia, New York City, Chicago, Boston, Washington, D.C., etc.). Hard Rock Cafe typically does not franchise cafe locations in the United States. All US cafes are corporate owned and operated, except for cafes in Tampa and Four Winds New Buffalo casino. However, in the transition of the Las Vegas Hard Rock Hotel property originally owned and then later sold to Rank by founder Peter Morton, Morton retained hotel naming rights west of the Mississippi. When Morton sold his Las Vegas Hard Rock Hotel to the Morgans Hotel Group, he also sold those naming rights, which then gave rise to two US franchised hotels (without cafes) in Albuquerque and Tulsa. The Albuquerque hotel no longer pays for the Hard Rock rights and reverted to its former name in June 2013. More hotels franchised from Morgan's are planned for Sioux City and Vancouver.
Document 4: Isaac Tigrett: Isaac Burton Tigrett (born November 28, 1948, Jackson, Tennessee) is an American businessman, best known as the co-founder of Hard Rock Café and House of Blues.

Document 6: Utrecht: In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.
Document 7: Hard Rock Cafe: In 1990, The Rank Group, a London-based leisure company, acquired Mecca Leisure Group and continued expansion of the concept in its geographic territory. Rank went on to purchase Hard Rock America from Peter Morton as well as Hard Rock Canada from Nick Bitove. After the completion of these acquisitions, Rank gained worldwide control of the brand. In March 2007, the Seminole Tribe of Florida acquired Hard Rock Cafe International, Inc. and other related entities from Rank for US$965 million.In 2008, anonymous members of the wait staff criticized the business because of its practice of paying them less than half the official minimum wage in the UK, with the business allocating tips to staff to bring their salaries within the law. Most customers, it was argued, do not realize that they are subsidizing a low wage when they give the tip.
Document 8: Mexico City: Other popular sites for pop-artist performances include the 3,000-seat Teatro Metropolitan, the 15,000-seat Palacio de los Deportes, and the larger 50,000-seat Foro Sol Stadium, where popular international artists perform on a regular basis. The Cirque du Soleil has held several seasons at the Carpa Santa Fe, in the Santa Fe district in the western part of the city. There are numerous venues for smaller musical ensembles and solo performers. These include the Hard Rock Live, Bataclán, Foro Scotiabank, Lunario, Circo Volador and Voilá Acoustique. Recent additions include the 20,000-seat Arena Ciudad de México, the 3,000-seat Pepsi Center World Trade Center, and the 2,500-seat Auditorio Blackberry.
Document 9: Habsburg Netherlands: Becoming the Seventeen Provinces in 1549, they were held by the Spanish Empire from 1556, and are therefore also known as the Spanish Netherlands from that time on. In 1581, the Seven United Provinces seceded to form the Dutch Republic; the remaining Spanish Southern Netherlands eventually passed on to Habsburg Austria. Finally, the Austrian Netherlands were annexed by the French First Republic in 1795.

Document 11: London: London has numerous venues for rock and pop concerts, including the world's busiest arena the o2 arena and other large arenas such as Earls Court, Wembley Arena, as well as many mid-sized venues, such as Brixton Academy, the Hammersmith Apollo and the Shepherd's Bush Empire. Several music festivals, including the Wireless Festival, South West Four, Lovebox, and Hyde Park's British Summer Time are all held in London. The city is home to the first and original Hard Rock Cafe and the Abbey Road Studios where The Beatles recorded many of their hits. In the 1960s, 1970s and 1980s, musicians and groups like Elton John, Pink Floyd, David Bowie, Queen, The Kinks, The Rolling Stones, The Who, Eric Clapton, Led Zeppelin, The Small Faces, Iron Maiden, Fleetwood Mac, Elvis Costello, Cat Stevens, The Police, The Cure, Madness, The Jam, Dusty Springfield, Phil Collins, Rod Stewart and Sade, derived their sound from the streets and rhythms vibrating through London.
Document 12: London: London was instrumental in the development of punk music, with figures such as the Sex Pistols, The Clash, and Vivienne Westwood all based in the city.

London is also a centre for urban music. In particular the genres UK garage, drum and bass, dubstep and grime evolved in the city from the foreign genres of hip hop and reggae, alongside local drum and bass.

Document 13: Elizabeth II: During her grandfather's reign, Elizabeth was third in the line of succession to the throne, behind her uncle Edward, Prince of Wales, and her father, the Duke of York. Although her birth generated public interest, she was not expected to become queen, as the Prince of Wales was still young, and many assumed that he would marry and have children of his own. When her grandfather died in 1936 and her uncle succeeded as Edward VIII, she became second-in-line to the throne, after her father. Later that year Edward abdicated, after his proposed marriage to divorced socialite Wallis Simpson provoked a constitutional crisis. Consequently, Elizabeth's father became king, and she became heir presumptive. If her parents had had a later son, she would have lost her position as first-in-line, as her brother would have been heir apparent and above her in the line of succession.
Document 14: Elizabeth II: Elizabeth was born in London to the Duke and Duchess of York, later King George VI and Queen Elizabeth, and was the elder of their two daughters. She was educated privately at home. Her father acceded to the throne on the abdication of his brother Edward VIII in 1936, from which time she was the heir presumptive. She began to undertake public duties during World War II, serving in the Auxiliary Territorial Service. In 1947, she married Philip, Duke of Edinburgh, with whom she has four children: Charles, Anne, Andrew, and Edward.
