Answer the question at the end by quoting:

Enrique Miguel Iglesias Preysler (; Spanish pronunciation: [en'rike mi'gel i'glesjas 'preizler]; born 8 May 1975) is a Spanish singer, songwriter, actor and record producer. He is widely regarded as the King of Latin Pop.
Iglesias was born in Madrid, Spain, and is the third and youngest child of Spanish singer Julio Iglesias and Filipina-Spanish socialite and magazine journalist Isabel Preysler. He was raised with two older siblings: Chabeli and Julio Jr.. One of his mother Preysler's aunts is actress Neile Adams, the first wife of American actor Steve McQueen, mother of actor Chad McQueen, and grandmother of actor Steven R. McQueen. His father Julio Iglesias' family are from Galicia and Andalusia - his father also claims Jewish and Puerto Rican ancestry on his mother's side. The parents divorced in 1979.  At first, Iglesias and his two siblings stayed with their mother, but in December 1981, Iglesias' grandfather, Dr. Julio Iglesias Puga, was kidnapped by the armed Basque terrorist group ETA. For their safety, Enrique and his brother Julio were sent to live with their father in Miami. There, they were brought up mostly by the nanny, Elvira Olivares, to whom he later dedicated his first album. He also lived in Belgrade, Yugoslavia, for one year with his mother. As his father's career kept him on the road, the young Iglesias was raised by the family nanny. He attended the prestigious Gulliver Preparatory School and later went on to study business at the University of Miami.  Iglesias did not want his father to know about his plans for a musical career and did not want his famous surname to help advance his career. He borrowed money from his family nanny and he recorded a demo cassette tape which consisted of a Spanish song and two English songs. Approaching his father's former publicist, Fernan Martinez, the two promoted the songs under the stage name 'Enrique Martinez' with the backstory of being an unknown singer from Guatemala. Iglesias was signed on to Fonovisa Records. After dropping out of college, he traveled to Toronto to record his first album.

IN: 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 "...

Glascock then joined Jethro Tull in 1976, after having met Ian Anderson when Carmen opened several dates for Jethro Tull on their War Child tour. Martin Barre said in the "Classic Artists Series" documentary, that his love for the band was unique, being a fan of Jethro Tull playing in the band. He played on the Jethro Tull albums Too Old to Rock 'n' Roll: Too Young to Die! (1976), Songs from the Wood (1977), Heavy Horses (1978), Bursting Out (1978), and on three tracks on Stormwatch (1979). In Jethro Tull he received no writing credits but sang backing vocals, and became the first harmony vocalist Jethro Tull had. He even sang on the album he was not credited on, Heavy Horses (1978).  Glascock replaced the longtime friend of Ian Anderson, Jeffrey Hammond. He also played electric guitar on-stage when Anderson's arrangement required it, as for instance in performances of "Skating Away (On the Thin Ice of the New Day)" from the Bursting Out live album, when the rest of the band was playing xylophone, glockenspiel and percussion.  Glascock's health problems became apparent when he was unable to complete the U.S. leg of the Heavy Horses tour, missing a transatlantic simulcast from Madison Square Garden. He played his last gig on 1 May 1979, in San Antonio, Texas, three years to the day of his first gig with Jethro Tull. Despite the diagnosis of heart valve damage caused by an infection, he continued his previous lifestyle, which involved heavy drinking, marijuana usage, and wild parties. His health continued to deteriorate. Ian Anderson gave him several warnings before finally laying him off with pay during the production of Stormwatch (1979), completing most of the bass guitar parts himself. During the subsequent promotional tour with replacement bass player Dave Pegg, Anderson learned of Glascock's death and had to break the news to the rest of the band. Glascock's close friend, drummer Barriemore Barlow, was devastated and left the band at the end of the tour. Mark Craney replaced Barlow.  The resulting dislocation, Ian Anderson's own artistic vision, and a decision from the label, prompted a complete overhaul of the lineup, leaving only Anderson and Martin Barre as full members, though Glascock's touring replacement on bass (Dave Pegg) was retained for the band's follow-up album in 1980.
