Lewis was the only female artist on the Members Only 1985 Happy Together Tour with The Buckinghams, the Turtles, Gary Lewis & the Playboys, and the Grass Roots. That same year the Buckinghams recorded their 1985 come-back album entitled A Matter Of Time which Laurie contributed lead vocals, back-up vocals and co-wrote "Made To Love You". Meanwhile, in 1995 she recorded with singer Gary Puckett on his 1995 album "Is This Love" which was released in Canada and Europe and later released in the U.S. on a compilation album called Timepiece and "This Is Love" in which both include a power duet of Gary and Laurie covering the Heart (band) ballad "Alone".
In 2013 Lewis was part of the all-star musical project Dick Wagner & the Rockers for St. Jude in which she shared lead vocals with Wagner, Mark Farner (Grand Funk Railroad), Jean Beauvoir, Merrilee Rush, and Trini Lopez, in a band that included drummer Danny Seraphine (Chicago), guitarists Jennifer Batten (Michael Jackson) and Elliott Easton (The Cars), as well as bassist Lee Sklar and a huge backing choir of well known musicians. The group recorded a digital single and a music video, "If I Had The Time (I Could Change The World)" with proceeds earmarked to benefit St. Jude Children’s Research Hospital.
