Abysmal Vapor
Supersniffer 2000 - robot fart detection device
Recording
Written by David Gilmour, Richard Wright and Polly Samson, it was sung by Gilmour and also features samples of Stephen Hawking's electronic voice, taken from a BT television advertisement (this same commercial would be sampled again in "Talkin' Hawkin'" from Pink Floyd's next and final studio album, The Endless River).[2] Gilmour chose to use the speech after crying to the commercial, which he described as "the most powerful piece of television advertising that I’ve ever seen in my life.”[3] The song also makes some use of the talk box guitar effect.
