Adrienne Anderson (maiden name Arzt, married Neal Anderson) has had a continuing association with Barry Manilow that goes back to his first album, released in July, 1973, and which featured their co-written "Could It Be Magic".
In late 1970 or very early 1971, Barry Manilow recorded Anderson's composition of "Amy". This was issued as Bell single 971 in February, 1971 as by Featherbed featuring Barry Manilow. This was the very first release of any kind for Manilow.
Anderson and Manilow have co-written approximately thirty songs that have been recorded. Two of their best-known collaborations are "Could It Be Magic" and "Daybreak". When Manilow was inducted into the Songwriters Hall of Fame in 2002, he made a point of attending with and crediting his co-writers, including Anderson. In 2010, Anderson was an invited guest at the premiere of Manilow's two-year engagement at the Paris Las Vegas.
Stemming from her association with Manilow, Anderson commenced writing with Melissa Manchester. She started co-writing with Manchester with the release of Manchester's second album, Bright Eyes (1974).
Anderson's collaboration with Peter Allen commenced in the mid-1970s, resulting in one of Allen's most-recognized songs, "I Go to Rio", which was first released in 1976. She also co-wrote "Love Crazy" with Allen, which was the opening track on Allen's 1977 live album, It Is Time for Peter Allen. She later co-write "Angels With Dirty Faces" with Allen, included on his 1979 album, I Could Have Been a Sailor.
In 1979, Anderson co-wrote "Déjà Vu" with Isaac Hayes, which was recorded by Dionne Warwick. The song, included on Warwick's first album for Arista Records, Dionne, was important to the revitalization of Warwick's career at that point.
Recent collaborations have included co-writing with noted songwriter, arranger and producer Leon Ware. Anderson also wrote the libretto for City Kid: The Musical, which premiered at Village Theatre in Issaquah, Washington, and subsequently opened in Los Angeles in 2007.
