 The poster advertising the event can be seen in the photo collage included in the album "Gong Live Etc", also released in 1977.The Gong lineup was a reunion of the "Angel's Egg"/"You"-era band, featuring the return of Daevid Allen, Gilli Smyth, Steve Hillage and Miquette Giraudy, who had left in 1975 and so were not part of the then-current Gong-Expresso (which would eventually change its name to Pierre Moerlen's Gong).Their set included most of the music from four albums - "Camembert Electrique" and the three albums of the "Radio Gnome Invisible" trilogy - therefore this album documents less than half of the performance and some songs are absent or incomplete.
