"Pow R. Toc H." is an instrumental, with vocal effects, by the English rock band Pink Floyd on their 1967 album The Piper at the Gates of Dawn.[2][3] In addition to the vocal effects, the piano is a prominent instrument in the piece.
Background
Toc H. was the army signallers' code for "TH", representing Talbot House, a club where officers and enlisted men were equals, which later became an interdenominational Christian fellowship organization serving the community.[4] (The emblem of Toc H. is an oil lamp, so a "power Toc H." would be an electric torch—probably with a dim bulb, as per the saying "as dim as a Toc H. lamp".)[citation needed]
