Speak is an 11 minute animated film that was known for it's intense flicker/strobe effect when shown in London area psychedelic clubs. That being the case Latham thought Pink Floyd would be a good match for its soundtrack. Near the end of the 10/67 De Lane Lea sessions (which produced Jugband Blues, Remember a Day, Vegetable Man and Beechwoods) the Syd led Floyd set aside some time to take a stab at recording a soundtrack for the film. A recording was completed and submitted to Latham but he rejected it.*
