Question:
Henry Franklin Winkler was born on October 30, 1945 on the West Side of Manhattan, New York, the son of homemaker Ilse Anna Marie (nee Hadra; 1913-2002) and lumber company president Harry Irving Winkler (1903-1995). His parents were German Jews who emigrated from Berlin to the U.S. in 1939, on the eve of World War II. Winkler said that his parents came to the U.S. for a six-month business trip but knew they were never going back. His father smuggled the only assets the family had left (family jewels disguised as a box of chocolates) that he carried under his arm.
Although Winkler had already shot the film The Lords of Flatbush, he was relatively unknown. In 1973, a year before that film was released, producer Tom Miller was instrumental in Winkler getting cast for the role of Arthur Herbert Fonzarelli, nicknamed "The Fonz" or "Fonzie", in Happy Days, which first aired in January 1974. For Happy Days, director/producer Garry Marshall originally had in mind a completely opposite physical presence. Marshall sought to cast a hunky, blonde, Italian model-type male in the role of Fonzie, intended as a stupid foil to the real star, Ron Howard. However, when Winkler interpreted the role in auditions, Marshall immediately snapped him up. According to Winkler, "The Fonz was everybody I wasn't. He was everybody I wanted to be." Winkler's character, though remaining very much a rough-hewn outsider, gradually became the focus of the show as time passed (in particular after the departure of Ron Howard). Initially, ABC executives did not want to see the Fonz wearing leather, thinking the character would appear to be a criminal. The first 13 episodes show Winkler wearing two different kinds of windbreaker jackets, one of which was green. As Winkler said in a TV Land interview, "It's hard to look cool in a green windbreaker". Marshall argued with the executives about the jacket. In the end, a compromise was made. Winkler could only wear the leather jacket in scenes with his motorcycle, and from that point on, the Fonz was never without his motorcycle until season 2. Happy Days ended its run in 1984.

Therion (formerly Blitzkrieg, Megatherion) is a Swedish symphonic metal band founded by Christofer Johnsson in 1988. Its name was inspired by the Celtic Frost album To Mega Therion. "To Mega Therion" is Greek for "The Great Beast" and was a title used by occultist Aleister Crowley. Originally a death metal band, Therion adjusted its musical style by adding orchestral elements, including choirs, classical musicians, and even a full orchestra at their concert performances.
On September 2006, Johnsson announced that recording was completed for a new album with 9 songs written by then drummer, Petter Karlsson. Gothic Kabbalah was released on 12 January 2007, and was followed with a tour through Europe, North and South America with Grave Digger and with support act Sabaton. Therion also toured Japan for the first time. The band's Warsaw gig was recorded for the live album and video set Live Gothic, which was released in 2008. In these times Therion held live shows that included local symphonic orchestras and choirs. The "Therion Goes Classic" show took place on 9 December 2006, in Bucharest, Romania. Another show followed at the Miskolc Opera Festival in Miskolc, Hungary on 16 June 2007, with future band member Lori Lewis as its featured vocalist. The first half of the show featured orchestral pieces from Dvorak, Verdi, Mozart, Saint-Saens and Wagner. The second half pulled from Therion's repertoire. The song "Clavicula Nox" was featured as a full orchestral version in the first half. The Bucharest concert was broadcast on Romanian television, and its first part was later released together with the entire Miskolc concert as the DVD/CD box set The Miskolc Experience in June 2009. In November-December 2007, Therion had a 20-year anniversary tour with 16 shows in Europe. Songs included "Kali Yuga" parts 1 and 2, the entire Theli album, and "Adulruna Rediviva". Part of the set list was determined from fan voting. Some songs were accompanied by keyboardist Ferdy Doernberg and a belly dancer on stage, and some of the shows featured also the ex-singers Piotr Wawrzeniuk and Mats Leven. The Budapest gig of the tour was recorded, but it was released only in February 2014 as a part of the DVD Adulruna Rediviva And Beyond.
