"Pow R. Toc H. was renamed "The Pink Jungle" in the 'Journey' part of The Man and the Journey. It's been said that Pow R. Toc H..was a conscious effort by the band to produce a sequel to 'Interstellar Overdrive'. The title, by Roger, is meaningless. Pow R. Toc H. was the army signallers code for TH, for the Talbot House, a club where officer and enlisted men were equals. It later became an Interdenominational Christian fellowship organization serving the community. Pow R. Toc H. was added for no other reason than it sounded right, according to R. Waters."
