This song is just too cool to be forgotten!? "Slow Walkin´Talk" was originally written for The Wilde Flowers by Brian Hopper (Hugh Hopper´s brother), and may be found on "Tales of Canterbury. The Wilde Flowers Story" (Voiceprint 1994). Graham Flight is singing on that version, with Robert Wyatt playing the drums.
On this Vimeo video, uploaded by the one and only Brian Jones (*cough*), Robert Wyatt is singing and playing piano, organ and drums, while Jimi Hendrix is playing the bass! This one was recorded in 1968, and has been released on both the Jimi Hendrix CD "Calling Long Distance" (Univibes 1992) and on the Robert Wyatt sampler "Flotsam Jetsam" (Rough Trade 1994).
