Question:
Krishnan Nair (25 July 1939 - 16 November 1980), better known by his stage name Jayan, was an Indian film actor, naval officer, stunt performer and cultural icon of the 1970s. He starred in over 120 Malayalam films. During his film career, he was primarily an action star and was particularly famous for his macho image and unique style. He was reputed for his chauvinistic appeal and well known for performing stunts of a dangerous nature on his own.
On 16 November 1980, Jayan was killed in an accident on the set of the movie Kolilakkam (English: Shockwave). The climactic scene of the movie was being filmed in Sholavaram, near Madras, Tamil Nadu. Jayan always performed his own stunts, and for this movie he was performing a particularly dangerous stunt that involved him boarding an airborne helicopter from a moving motorbike. The shot was accepted by the director in the first take; altogether three shots were filmed.  According to the film's production executive, Jayan insisted on yet another re-take as he was not satisfied with its perfection. During the re-take, the helicopter lost its balance and crashed along with Jayan who was hanging onto the landing skids, and he later succumbed to his injuries.  After his death was confirmed, a slide was added during the theatre show of his movie Deepam, which was running in packed houses, informing his death to the viewers who witnessed it with absolute shock and disbelief. A large number of his fans burst into tears and ran out of the buildings, while many continued to watch the movie, refusing to believe it and taking it for an ingenious promotion for some upcoming project.  Jayan's body was taken to Trivandrum via aeroplane and later it was taken to his home in Quilon, where he was cremated. Thousands paid homage to the late actor, and the police had to take huge measures to deal with the crowds. His mother Bharathiyamma became bedridden after this incident, and she too died two years later.  Some conspiracy theories emerged regarding the circumstances of his death, primarily because the pilot and his co-star Balan K. Nair, who was in the helicopter, survived with minor or no injuries. Nevertheless, it has been confirmed as a genuine accident.

Answer the question at the end by quoting:

Frank Vincent Zappa (December 21, 1940 - December 4, 1993) was an American musician, composer, activist and filmmaker. His work is characterized by nonconformity, free-form improvisation, sound experiments, musical virtuosity, and satire of American culture. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and musique concrete works, and produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. Zappa also directed feature-length films and music videos, and designed album covers.
Zappa and the Mothers of Invention returned to Los Angeles in mid-1968, and the Zappas moved into a house on Laurel Canyon Boulevard, only to move again to one on Woodrow Wilson Drive. This was Zappa's home for the rest of his life. Despite being a success with fans in Europe, the Mothers of Invention were not faring well financially. Their first records were vocally oriented, but Zappa wrote more instrumental jazz and classical oriented music for the band's concerts, which confused audiences. Zappa felt that audiences failed to appreciate his "electrical chamber music".  In 1969 there were nine band members and Zappa was supporting the group himself from his publishing royalties whether they played or not. 1969 was also the year Zappa, fed up with MGM Records' interference, left them for Warner Bros. Records' Reprise subsidiary where Zappa/Mothers recordings would bear the Bizarre Records imprint.  In late 1969, Zappa broke up the band. He often cited the financial strain as the main reason, but also commented on the band members' lack of sufficient effort. Many band members were bitter about Zappa's decision, and some took it as a sign of Zappa's concern for perfection at the expense of human feeling. Others were irritated by 'his autocratic ways', exemplified by Zappa's never staying at the same hotel as the band members. Several members played for Zappa in years to come. Remaining recordings with the band from this period were collected on Weasels Ripped My Flesh and Burnt Weeny Sandwich (both released in 1970).  After he disbanded the Mothers of Invention, Zappa released the acclaimed solo album Hot Rats (1969). It features, for the first time on record, Zappa playing extended guitar solos and contains one of his most enduring compositions, "Peaches en Regalia", which reappeared several times on future recordings. He was backed by jazz, blues and R&B session players including violinist Don "Sugarcane" Harris, drummers John Guerin and Paul Humphrey, multi-instrumentalist and previous member of the Mothers of Invention Ian Underwood, and multi-instrumentalist Shuggie Otis on bass, along with a guest appearance by Captain Beefheart (providing vocals to the only non-instrumental track, "Willie the Pimp"). It became a popular album in England, and had a major influence on the development of the jazz-rock fusion genre.
