Janet Ferguson was part of the 2401 Laurel Canyon Boulevard 'Log Cabin Commune' scene in the mid 1960's and later, when Zappa took residency of The Cabin on returning from New York in 1968. The photo [taken Oct 1969 outside the Log Cabin] shows her on the left, with 'groupie' Lucy Offerall of the GTO's, aka Miss Lucy [see Permanent Damage album].

Born Janet Neville-Ferguson, she married Paul Hof, who was a 'roadie' and technician on Zappa albums such as 200 Motels, Over-Nite Sensation & The Grand Wazoo. Ferguson also features on the latter album, providing vocals.
(Offerall & Ferguson feature in the Zappa film 200 Motels, on which Paul Hof was a technician. Paul Hof's head is one of the 2-headed 'roadie' on the cover of Over-Nite Sensation, the other head is that of Jay Sloatman, brother of Zappa's wife Gail).
Janet Ferguson also provided vocals on Burnt Weeny Sandwich & Waka/Jawaka by Zappa and has also been referred to within album credits/write-ups as Janet Gabby Furggy Ferguson. An oblique reference is also made to her in the star 'Henna Brillo' in the 'Universe' illustration by Cal Schenkel on the cover of One Size Fits All.

She has also provided vocals on solo albums by George Duke.
