Pink Floyd - Is There Anybody Out There? - Vinyl 1979

The first half of the piece has the same concept of "Hey You", being a distress call from Pink. Musically, it's a droning bass synthesizer with various sound effects layered on top, and a repeating chorus of "Is there anybody out there?". The shrill siren-like sound effect used during this song is also used in an earlier Pink Floyd work, "Echoes". The noise is mimicking a seagull cry. The seagull noise was created by David Gilmour using a wah-wah pedal with the guitar and output leads plugged in the wrong way round.
