Grantchester Meadows
Off of Pink Floyd's UmmaGumma, this is track five, Grantchester Meadows.
According to Wikipedia -- "It was written and performed entirely by Roger Waters. The song features Waters' lyrics accompanied by an acoustic guitar, while a tape loop of a skylark chirps in the background throughout the entire song. At approximately 4:13, the sound of a honking goose is temporarily introduced, followed by the sound of it taking off."
And - "The song is noted for its use of stereo effects and sound panning to create an illusion of space and depth. This is most noticeable when listening with headphones. The background chirping birds flicker across the channels. The honking goose is first heard in the extreme left channel and the noise of its flight slowly panning to the right. Similarly, considering the song's idyllic setting, a fly can be heard buzzing close to the listener, and around from mid-right to mid-left channel, at the end of the song, followed by someone's footsteps coming in from far left and slowly panning to the right, as if walking down a flight of stairs and across a room to finally swat and kill the fly with a loud "smack" in the center (an ending that segues into the following song, "Several Species...")."
