Lennon was, between 1970 and 1971, associated with Frank Zappa's band as a substitute musician. She wrote a book of her time with the group "Being Frank: My Time with Frank Zappa" [ISBN 978-1879395411].

Among her other literary works are: "The Sagebrush Bohemian: Mark Twain In California" [ISBN 978-1557782649] and "Alfred Jarry: The Man with the Axe" (illustrated by Bill Griffith) . A section of the latter work features on the Sonic Arts Network CD "'Pataphysics", a selection of French and English songs, electronic and instrumental music.

Lennon moved from L.A to New York City in 2000 and has also released a CD "Reinventing The Wheel", on which Zappa's sister 'Candy' [Patricia] also features.
