Question: Who is the spouse of the producer of Absolutely Free?

full_context: Document 1: Scheila Gonzalez: Scheila Gonzalez (born August 5, 1971 in Los Angeles, California) is an American, Grammy winning multi-instrumentalist and music educator. She is best known for playing the saxophone and other instruments with artists such as Dweezil Zappa, Alex Acuña, Ray Parker Jr., and many others. She currently plays alto saxophone in the all-female DIVA Jazz Orchestra and is a full-time member of the Zappa Plays Zappa world tour, in which she sings and plays several instruments.
Document 2: Hard rock: Groups that emerged from the American psychedelic scene about the same time included Iron Butterfly, MC5, Blue Cheer and Vanilla Fudge. San Francisco band Blue Cheer released a crude and distorted cover of Eddie Cochran's classic "Summertime Blues", from their 1968 debut album Vincebus Eruptum, that outlined much of the later hard rock and heavy metal sound. The same month, Steppenwolf released its self-titled debut album, including "Born to Be Wild", which contained the first lyrical reference to heavy metal and helped popularise the style when it was used in the film Easy Rider (1969). Iron Butterfly's In-A-Gadda-Da-Vida (1968), with its 17-minute-long title track, using organs and with a lengthy drum solo, also prefigured later elements of the sound.
Document 3: Gordon MacRae: He was married to Sheila MacRae from 1941 until 1967; the couple were the parents of four children: actresses Heather and Meredith MacRae, and sons William Gordon MacRae and Robert Bruce MacRae. Two of the children, Meredith MacRae and Robert Bruce MacRae, predeceased their mother, Sheila. Sheila divorced Gordon in order to marry producer Ronald Wayne.
Document 4: The Velvet Underground: The Velvet Underground was an American rock band formed in 1964 in New York City by singer/guitarist Lou Reed, multi-instrumentalist John Cale, guitarist Sterling Morrison, and drummer Angus MacLise (replaced by Moe Tucker in 1965). The band was initially active between 1965 and 1973, and was briefly managed by the pop artist Andy Warhol, serving as the house band at the Factory and Warhol's "Exploding Plastic Inevitable" events from 1966 to 1967. Their debut album, "The Velvet Underground & Nico" (with German-born singer and model Nico), was released in 1967 to critical indifference and poor sales but has become critically acclaimed; in 2003, "Rolling Stone" called it the "most prophetic rock album ever made."
Document 5: Free Jazz: A Collective Improvisation: Free Jazz: A Collective Improvisation is the sixth album by jazz saxophonist and composer Ornette Coleman, released on Atlantic Records in 1961, his fourth for the label. Its title established the name of the then-nascent free jazz movement. The recording session took place on December 21, 1960, at A&R Studios in New York City. The sole outtake from the album session, "First Take," was later released on the 1971 compilation "Twins".
Document 6: Gizella Lutz: Ferenc Szálasiné (née Gizella Lutz or "Lucz"; 21 October 1906 – 1992) was the longtime companion and, for a brief time, wife, of Ferenc Szálasi who served as Leader of the Hungarian Nation and "de facto" Prime Minister of Hungary at the end of the Second World War. They were married on 29 April 1945, on the wedding day of Adolf Hitler and Eva Braun. She was captured by the United States Army on 3 July 1945 and transferred to Hungary. Her husband was executed on 12 March 1946. She was sentenced to twelve years imprisonment on 3 December 1953. She was released in 1958.
Document 7: Muammar Gaddafi: Gaddafi married his first wife, Fatiha al-Nuri, in 1969. She was the daughter of General Khalid, a senior figure in King Idris' administration, and was from a middle-class background. Although they had one son, Muhammad Gaddafi (b. 1970), their relationship was strained, and they divorced in 1970. Gaddafi's second wife was Safia Farkash, née el-Brasai, a former nurse from Obeidat tribe born in Bayda. They met in 1969, following his ascension to power, when he was hospitalized with appendicitis; he claimed that it was love at first sight. The couple remained married until his death. Together they had seven biological children: Saif al-Islam Gaddafi (b. 1972), Al-Saadi Gaddafi (b. 1973), Mutassim Gaddafi (1974–2011), Hannibal Muammar Gaddafi (b. 1975), Ayesha Gaddafi (b. 1976), Saif al-Arab Gaddafi (1982–2011), and Khamis Gaddafi (1983–2011).

Document 8: Inca Roads (song): "Inca Roads" is the opening track of the Frank Zappa and the Mothers of Invention 1975 album, "One Size Fits All". The song features unusual time signatures, lyrics and vocals. The marimba-playing of Zappa's percussionist Ruth Underwood is featured prominently. The song was played in concert from 1973 to 1976, 1979 and 1988.
Document 9: Absolutely Free: Absolutely Free is the second studio album by the American rock band the Mothers of Invention, led by Frank Zappa, released in 1967. "Absolutely Free" is, again, a display of complex musical composition with political and social satire. The band had been augmented since "Freak Out!" by the addition of woodwinds player Bunk Gardner, keyboardist Don Preston, rhythm guitarist Jim Fielder and drummer Billy Mundi. Fielder quit the group before the album was released and his name was removed from the album credits.
Document 10: The Best Band You Never Heard in Your Life: The Best Band You Never Heard in Your Life is a double-disc live album by American musician Frank Zappa, released in 1991. The album was one of three to be recorded during the 1988 world tour, along with "Broadway the Hard Way" and "Make a Jazz Noise Here". Each of these three accounts of the 1988 tour has a different emphasis: "Broadway the Hard Way" mainly consists of new compositions; "Make a Jazz Noise Here" is a sampler of classic Zappa tunes, most of them instrumental; and "The Best Band..." devotes itself to covers. Some of these are unlikely (such as "Stairway to Heaven" by Led Zeppelin), while many are from Zappa's extensive back catalogue. His mid-1970s output is emphasized in the selection, but there is also some material from the Mothers of Invention's late 1960s recordings and one song ("Lonesome Cowboy Burt") from "200 Motels". It was re-issued in 1995 and 2012 along with his entire catalogue.
Document 11: Gail Zappa: Adelaide Gail Zappa ( Sloatman; January 1, 1945 – October 7, 2015) was the wife of musician and composer Frank Zappa and the trustee of the Zappa Family Trust. They met in Los Angeles in 1966 and married while she was pregnant with their first child, Moon, followed by Dweezil, Ahmet and Diva.
Document 12: Mothership Connection: Mothership Connection is the fourth album by American funk band Parliament, released on December 15, 1975 on Casablanca Records. This concept album of P-Funk mythology is usually rated as one of Parliament's best. "Mothership Connection" was the first P-Funk album to feature Maceo Parker and Fred Wesley, who had left The J.B.'s, James Brown's backing band. "Mothership Connection" became Parliament's first album to be certified gold and later platinum. The Library of Congress added the album to the National Recording Registry in 2011, declaring "The album has had an enormous influence on jazz, rock and dance music."
Document 13: Elizabeth Glaser: Elizabeth Glaser (Born Elizabeth Meyer; – ) was a major American AIDS activist and child advocate married to actor and director Paul Michael Glaser. She contracted HIV very early in the modern AIDS epidemic after receiving an HIV-contaminated blood transfusion in 1981 while giving birth. Like other HIV-infected mothers, Glaser unknowingly passed the virus to her infant daughter, Ariel, through breastfeeding. Ariel was born in 1981 and died in 1988. The Glasers' son, Jake, born in 1984, contracted HIV from his mother "in utero", but has lived into adulthood. Elizabeth Glaser died in 1994.
Document 14: Playground Psychotics: Playground Psychotics is a two-CD live album by Frank Zappa and the Mothers of Invention. It was originally released in 1992 through his mail order label, Barking Pumpkin, and was re-released in 1995 through Rykodisc. The album features recordings of Zappa and his band, the Mothers of Invention, around the time of the film "200 Motels". The live material on "Playground Psychotics" is interspersed with excerpts from taped conversations among band members whilst on tour, and the release includes three conceptual sections: "A Typical Day on the Road, Part 1", a collage of dialogue which opens the first disc; "A Typical Day on the Road, Part 2", which opens the second disc and "The True Story of 200 Motels", which appears at the end of disc two. The album also includes a live session with John Lennon and Yoko Ono, an alternate mix of which appears on Lennon's "Some Time in New York City" (1972).
