The Beatles’ Famous Runoff Groove Found On ‘Sgt. Pepper’ Forwards…And Backwards

The Beatles “Sgt. Pepper’s Inner Groove” from the mono UK Parlophone LP, 1967, first played normal forwards for a little over a minute … then listen to what happen when the reverse button is hit. It plays backwards for another minute. If you listen closely you might be able to hear the dog whistle that precedes the inner groove weirdness.
