"Voodoo Ray" is a 1988 Acid House single by Gerald Simpson, recording under the name A Guy Called Gerald. The single was released the UK in 1988, in the 7" and 12" vinyl formats, on the Rham! label. It reached number 12 in the UK singles chart, and was the best selling independently released single in 1989. It was released in the USA in 1989 by Warlock Records. It also appeared on A Guy Called Gerald's 1988 album Hot Lemonade, and a rerecorded version called "Voodoo Ray Americas" appeared on Gerald's 1990 album Automanikk, which was released on Columbia/CBS Records.
The song contains samples of comedians Peter Cook and Dudley Moore, taken from the first Derek and Clive LP, Derek and Clive (Live), specifically the Bo Duddley sketch.   "Voodoo Ray" combines a sample of Peter Cook delivering the phrase "voodoo rage", truncated due to the recording equipment's lack of memory, and also Dudley Moore forcefully delivering the word "later." In each case the samples are shifted in pitch, and electronically processed. The vocal was sung by Nicola Collier, who lived on Gerald's estate and had worked on other tracks with him.
