The Beatles - Sgt Pepper's Inner Groove (first forwards, then 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 I hit the reverse button, then 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.
