full_context: Document 1: MV Nino Bixio: MV "Nino Bixio" was an Italian cargo ship. Giovanni Ansaldo and Company of Genoa built her in 1941 for the Garibaldi group, a Genoese shipping company. A Royal Navy submarine torpedoed and damaged her in 1942, killing 336 Allied prisoners of war who were aboard her. The ship survived, was repaired, and continued in merchant service until 1970. She was scrapped at La Spezia in 1971.
Document 2: Professional wrestling: In Latin America and English-speaking countries, most wrestlers (and other on-stage performers) portray character roles, sometimes with personalities wildly different from their own. These personalities are a gimmick intended to heighten interest in a wrestler without regard to athletic ability. Some can be unrealistic and cartoon-like (such as Doink the Clown), while others carry more verisimilitude and can be seen as exaggerated versions of the performer's real life personality (such as Chris Jericho, The Rock, John Cena, Stone Cold Steve Austin, and CM Punk). In lucha libre, many characters wear masks, adopting a secret identity akin to a superhero, a near-sacred tradition.

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.

Document 9: 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.
