I have a test where I am given the following article, what is an answer for the question: What is the name of the album that represented a collection of doo-wop songs? ?

The Mothers of Invention played in New York in late 1966 and were offered a contract at the Garrick Theater (at 152 Bleecker Street, above the Cafe au Go Go) during Easter 1967. This proved successful and Herb Cohen extended the booking, which eventually lasted half a year. As a result, Zappa and his wife, along with the Mothers of Invention, moved to New York. Their shows became a combination of improvised acts showcasing individual talents of the band as well as tight performances of Zappa's music. Everything was directed by Zappa using hand signals. Guest performers and audience participation became a regular part of the Garrick Theater shows. One evening, Zappa managed to entice some U.S. Marines from the audience onto the stage, where they proceeded to dismember a big baby doll, having been told by Zappa to pretend that it was a "gook baby".Zappa uniquely contributed to the avant-garde, anti-establishment music scene of the 1960s, sampling radio tape recordings and incorporating his own philosophical ideals to music and freedom of expression in his pieces. Bands such as AMM and Faust also contributed to the radio sampling techniques of the 1960s. Situated in New York, and only interrupted by the band's first European tour, the Mothers of Invention recorded the album widely regarded as the peak of the group's late 1960s work, We're Only in It for the Money (released 1968). It was produced by Zappa, with Wilson credited as executive producer. From then on, Zappa produced all albums released by the Mothers of Invention and as a solo artist. We're Only in It for the Money featured some of the most creative audio editing and production yet heard in pop music, and the songs ruthlessly satirized the hippie and flower power phenomena. He sampled plundered surf music in We're only in It for the Money, as well as the Beatles' tape work from their song Tomorrow Never Knows. The cover photo parodied that of the Beatles' Sgt. Pepper's Lonely Hearts Club Band. The cover art was provided by Cal Schenkel whom Zappa met...
