Pink Floyd - The Happiest Days of Our Lives - Vinyl 1979

The lead instrument is an electric guitar with an added delay effect, playing roots (mostly D, G and A over a melody in D minor). The bass and guitar figure heard during the verses, G to A, is similar to the one in "Waiting for the Worms", a song that appears much later in the album. During the transition to "Another Brick in the Wall, Pt. 2", the key shifts from D minor to the relative major, F major, with dramatic drum rolls and harmony vocals.
