input: Christensen made his acting debut in September 1993, when, at the age of 12, he played a supporting role on the German-Canadian television series Macht Der Leidenschaft/Family Passions. The following year, he had a minor role in John Carpenter's In the Mouth of Madness. From 1995 through 1999, he appeared in several films and television series, including Harrison Bergeron, Forever Knight, Goosebumps, The Virgin Suicides, and Are You Afraid of the Dark? He acquired wider notice while starring in Fox Family Channel's television series Higher Ground in 2000, portraying a teen who was sexually molested by his stepmother, and then turned to drugs in his despair. Christensen's critically acclaimed portrayal of a misunderstood teenager in Life as a House (2001) earned him Golden Globe and SAG Award nominations, as well as the National Board of Review's award for Breakthrough Performance of the Year. However, the performance did not receive widespread public notice. In 2002, Christensen made his London theatre debut with Jake Gyllenhaal and Anna Paquin in This Is Our Youth. He went on to receive good reviews for 2003's Shattered Glass, which tells the true story of journalist Stephen Glass, who was discovered to be fabricating stories as a writer for The New Republic and other publications. Peter Travers of Rolling Stone wrote, "Hayden Christensen is sensational as Glass, finding the wonder boy and the weasel in a disturbed kid flying high on a fame he hasn't earned." In 2005, Christensen made his Broadway debut when he appeared briefly in a 10-minute play. In 2005, he took part in the fifth annual "24 Hour Plays" benefit, which raises cash for nonprofit groups in the Big Apple.

Problem: Background: John Glascock (2 May 1951 - 17 November 1979) was the bass guitarist, backing vocalist, and occasional lead vocalist for the progressive rock band Carmen. He was also the bass guitarist and backing vocalist for the progressive rock band Jethro Tull from December 1975 until August 1979. He died in 1979, at the age of 28, as a result of a congenital heart valve defect, which was worsened by an infection caused by an abscessed tooth. In a September 1978 'Guitar Player' interview, Ritchie Blackmore had said "...
Context: In 1973 he joined Carmen. With them, John Glascock played bass guitar, sang backup vocals, occasionally played synthesizers, and even sang lead vocals on a few songs. These songs include "The City", "Dancing On a Cold Wind" (sharing lead vocals with David Allen), and "The Horseman" (sharing vocal duties with all of Carmen), all from the album Dancing on a Cold Wind (1975). He also sang on the track "High Time" from the album The Gypsies (1976). Glascock's basslines in Carmen were often technical and unusual. They were key to Carmen's unique sound. Unlike his work in Jethro Tull, Glascock utilized effects in his sound while with Carmen, like a fuzz pedal in the song "Viva Mi Sevilla". Glascock had only one writing credit on the first album recorded by Carmen, Fandangos in Space (1974), the short track "Retirando". He shared this writing credit with the rest of the band. His writing expanded greatly by the time of the second album, Dancing on a Cold Wind (1975). On this album he had a writing credit for three songs, "Viva Mi Sevilla" (which he shares with the rest of the band), "Purple Flowers" (which he shares with Roberto Amaral), and "Remembrances" (which he shares with the rest of the band). His writing had reached a climax by the time of Carmen's third and final album, The Gypsies (1976). On this album he wrote "High Time" by himself, and sang lead vocals on it. He and the rest of the band also share a writing credit on the instrumental track "Margarita".
Question: how did the carmen story begin?
Answer: In 1973 he joined Carmen.

Question: Leonard, the fifth of seven children of Cicero and Getha Leonard, was born in Wilmington, North Carolina. He was named after Ray Charles, his mother's favorite singer. The family moved to Washington, D.C., when he was three, and they settled permanently in Palmer Park, Maryland when he was ten. His father worked as a supermarket night manager and his mother was a nurse.

When Leonard decided to turn professional, Janks Morton introduced him to Mike Trainer, a friend of his who was an attorney. Trainer talked 24 of his friends and clients into underwriting Leonard's career with an investment of $21,000 to be repaid within four years at 8% interest. Trainer then made Leonard the sole stockholder in Sugar Ray Leonard, Inc. Angelo Dundee, Muhammad Ali's trainer, was brought in to be Leonard's trainer and manager. Many of the people being considered wanted absolute control and a cut somewhere near the manager's traditional 33%. Dundee had a different proposition. Although he would prescribe the training procedures, he would leave the day-to-day work to Dave Jacobs and Janks Morton. He would also choose Leonard's opponents. For his services, Dundee would get 15% of Leonard's purse. Leonard made his professional debut on February 5, 1977 before a crowd of 10,270 at the Civic Center in Baltimore. He was paid $40,044 for the fight. His opponent was Luis "The Bull" Vega, whom he defeated by a six-round unanimous decision. After the fight, Leonard paid back his $21,000 loan to the investors. In his fourteenth professional fight, Leonard fought his first world-ranked opponent, Floyd Mayweather, who was ranked seventeenth. The fight took place on September 9, 1978. Leonard won by a tenth-round knockout. A month later, Leonard defeated his old amateur nemesis Randy Shields by a ten-round unanimous decision. On August 12, 1979, Leonard knocked out Pete Ranzany in four rounds to win the NABF Welterweight Championship. The following month, he made his first title defense against Andy Price. Many felt that Price would give Leonard a tough fight, but Leonard took him out in the first round, advancing his record to 25-0 with 16 knockouts.
