While selling the International Herald Tribune around Le Chat Qui Pêche and the Latin Quarter, he met Terry Riley and also gained free access to the jazz clubs in the area.
After meeting up with William S. Burroughs, and inspired by philosophies of Sun Ra, he formed free jazz outfit the Daevid Allen Trio ('Daevid' having been adopted as an affectation of David), which included his landlord's son, 16-year-old Robert Wyatt.
Both projects were cut short as the two took part in the 1968 Paris protests which swept the city, handing out teddy bears to the police and reciting poetry in pidgin French.
Returning to Paris in August 1969, they were offered the chance to make an album by the BYG Actuel label and so formed a new Gong band and recorded Magick Brother, released in March 1970.
This group performed on the soundtrack to the film Continental Circus, poet Dashiell Hedayat's Obsolete and Gong's nominal second studio album, Camembert Electrique.
In October, Allen, Smyth and the rest of Gong moved into an abandoned 12-room hunting lodge called Pavilion du Hay, near Voisines and Sens, 120 km south-east Paris.
Later Steve Hillage and Pierre Moerlen also joined to record the Radio Gnome Invisible" trilogy which consisted of Flying Teapot, Angel's Egg and You.
Allen left Gong in April 1975 and went on to record three more solo albums, Good Morning (1976), Now Is the Happiest Time of Your Life (1977) and N'existe pas!
During these years, he lived in a hippie collective in Deià and contributed to the production of The Book of Am, an album by the band Can am des puig, loaning them a four-track TEAC reel-to-reel tape recorder.
In late May 1977, Allen performed and recorded as Planet Gong, then reformed the "Radio Gnome Trilogy" version of the group for a one-off show at the Hippodrome, Paris, France.
In 1996 he made a guest appearance on the track "Chant of the Twisted Mystics" on the album "Escape From Awkward Caucasia" by Byron Bay psychedelic / space rock band Freaks of Nature.
He also recorded with Spirits Burning, a space rock supergroup whose members include Alan Davey, Bridget Wishart, Karl E. H. Seigfried, and Simon House.
Some of Daevid Allen's most experimental work was with the long running Los Angeles noise band Big City Orchestra, including live performances and more than a half dozen CD releases.
Further Gong concerts were held in London in June 2008, featuring many of the same line-up, including Allen himself, Gilli Smyth, Steve Hillage, Miquette Giraudy, and Mike Howlett.
