Question: Who was the spouse of the producer of The Lost Episodes?

full_context: Document 1: 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 2: 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.

Document 3: 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: The Lost Episodes: The Lost Episodes is a 1996 posthumous album by Frank Zappa which compiles (with the exception of "I Don't Want to Get Drafted" and "Any Way the Wind Blows") previously unreleased material.

Document 13: Dancin' Fool: "Dancin' Fool" is a song by Frank Zappa from his 1979 album "Sheik Yerbouti". It was the first of two singles released from the album, followed by the second single "Bobby Brown (Goes Down)." The song premiered on stage on the 30th of October 1977 (as can be heard on the Halloween '77 boxset released in 2017). Much like "Zoot Allures'" closing track "Disco Boy", it mocks the disco culture of the 1970s, but unlike "Disco Boy", the song directly focuses on the dancing aspect of the culture. Specifically, the character Zappa is singing as cannot help but dance, despite how awful he is at it. He refers to his dancing as "social suicide" and says, "The beat goes on and I'm so wrong." He mentions as part of the reason for his bad dancing that, "One of my legs is shorter than the other," a reference to a severe injury Zappa sustained at the Rainbow Theatre in 1971. Soon, it inspired crazy dance moves to mock disco dancers, and this was especially relevant, as disco was on its decline. "Dancin' Fool" charted at 45 on the U.S. charts, making it Zappa's 2nd highest charting single, behind his 1982 song, "Valley Girl". The song was nominated for the Grammy award for "Best Male Vocal", but did not win. It was included on Zappa's best of compilation, "Strictly Commercial".
Document 14: Find Her Finer: "Find Her Finer" is a 1976 single by Frank Zappa from the album "Zoot Allures". The song was recorded with Zappa's lips extremely close to the microphone, creating an intimate sound. Roy Estrada provided falsetto vocals to create a comic effect to the song. It was intended to be the lead single for "Zoot Allures", but failed to chart, unlike its other single "Disco Boy". A live and sped up jazz version can also be found on the album "The Best Band You Never Heard in Your Life". It was played in concert in 1976 and 1988.
Document 15: 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). He also adopted two children, Hanna Gaddafi and Milad Gaddafi.
