I've got a feeling

Overhearing a take of I’ve Got A Feeling from the rehearsals to Beatles’ rooftop concert, I came upon the following wonderful quote on the song:

“The harmony is dominated by that Beatlesque neo-Blues quartet of chords: I, IV, V, and flat-VII, supplemented by the cliché of a chromatic stream of diminished triads played over a pedal point.”

Couldn’t have said it better myself.

Even if I knew music theory.
