Although The Song Is An Instrumental, The Threat (One Of These Days, I'm Going To Cut You Into Little Pieces), A Rare Vocal Contribution By Drummer Nick Mason Was Recorded Through A Ring Modulator And Slowed Down To Create An Eerie Effect. It Was Aimed At Sir Jimmy Young, The Then BBC Radio 1 And Radio 2 DJ Whom Pink Floyd Supposedly Disliked Because Of His Tendency To Babble. During The Early 1970's Concerts, The Floyd Somethings Played A Sound Collage Of Clips From Young's Radio Show That Was Edited To Sound Completely Nonsensical, Thus Figuratively "Cutting Him Into Little Pieces".
