Ike Willis: Isaac "Ike" Willis (born November 12, 1955) is an American vocalist and guitarist who was a regular member of Frank Zappa's studio and touring bands from 1978 until the last tour in 1988.  He did not tour with Zappa in 1981 and 1982 because he wanted to be home for the birth of his two children, but returned to touring with Zappa for his final two tours in 1984 (which Zappa intended at the time to be his final tour) and 1988.  He currently tours with the Frank Zappa tribute bands Bogus Pomp, Ossi Duri, Project/Object, Pojama People, Ugly Radio Rebellion and ZAPPATiKA.  He also performed several times with the Brazilian Zappa cover band, The Central Scrutinizer Band, The Muffin Men, and with the Italian bands and Elio e le Storie Tese .  Additionally, he has appeared multiple times at the annual Zappanale Festival in Bad Doberan, Germany.  He is most recognized for his involvement in Zappa records such as playing Joe in "Joe's Garage", providing vocals on "Tinsel Town Rebellion", "You Are What You Is", and "The Man from Utopia", and as the title character and narrator in Zappa's off-Broadway-styled conceptual musical "Thing-Fish".

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 sometime around Halloween in 1975, but was only part of the live set for three months; typically it was played alongside "Approximate", as the two songs displayed an odd contrast and Zappa embraced oddities.  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".

Jewish Princess (song): "Jewish Princess" is a song by Frank Zappa released on his album "Sheik Yerbouti" in 1979.  The song is a humorous look at the Jewish-American princess stereotype which attracted attention from the Anti-Defamation League, to which Zappa denied an apology, arguing: "Unlike the unicorn, such creatures do exist — and deserve to be 'commemorated' with their own special opus".  In an interview with Spin magazine he was almost offended saying, "…as if to say there is no such thing as a Jewish Princess.  Like I invented this?"
