the re-pressing, the company deleted "Runnin' Round This World" (which had appeared on early mono pressings), because executives objected to the word "trip" in the lyrics. For similar reasons, RCA Victor substituted altered versions for two other tracks: "Let Me In", changing the line "I gotta get in/you know where" to "you shut your door/now it ain't fair." In the same song, they also switched the lyric "Don't tell me you want money" to "Don't tell me it ain't funny". "Run Around" was also edited, changing the line "flowers that sway as you lay under me" to "flowers that sway as you stay here by me". The original pressings of the LP featuring "Runnin' 'Round This World" and the uncensored versions of "Let Me In" and "Run Around" are collectors items. Signe Anderson gave birth to her daughter in May 1966, and in October she announced her departure from the band. Her final performance with the Airplane took place at the Fillmore on October 15, 1966. A recording of the performance was in 2010 released as a live album, subtitled Signe's Farewell. 1966–1967: Commercial breakthrough The following night, Anderson's replacement Grace Slick made her first appearance. Slick was already well known to the band—she had attended the Airplane's debut gig at the Matrix in 1965 and her previous group, the Great Society, had often supported the Airplane in concert. Slick's recruitment proved pivotal to the Airplane's commercial breakthrough—she possessed a powerful and supple contralto voice that complemented Balin's and was well-suited to the group's amplified psychedelic music. A former model, her good looks and stage presence greatly enhanced the group's live impact. "White Rabbit" was written by Slick while she was still with The Great Society. The first album she recorded with Jefferson Airplane was Surrealistic Pillow, its 1967 breakout album. Slick provided two songs from her previous group: her own "White Rabbit" and "Somebody to Love", written by her brother-in-law Darby Slick. Both songs became breakout successes for Jefferson Airplane and have ever since been associated with that band. The Great Society had recorded an early version of "Somebody to Love" (under the title "Someone to Love") as the B-side of their only single, "Free Advice", produced by Sylvester Stewart (soon to become famous as Sly Stone). It reportedly took more than 50 takes to achieve a satisfactory rendition. The Great Society split up in late 1966 and played
