You know that little bit at the end of the song, after all the music ends, there's that short little, one-second, cut up, edited sound clip that sounds like a clip of somebody's voice edited up? I was able to use Audacity to slow down and reverse that little bit, and I found out that there's a little hidden message. When slowed down and reversed, you can hear a man (presumably Andy, it sounds like his voice), saying "Hey, go fuck yourself with your atom bomb". Probably a little bit of social commentary there, and the cheekiness sounds 100% Andy. XD
What about to say about this song will likely get me fire & brimstone from many other people, including An, er, 'Sir John Johns' himself if he were to read this. But, ah, here goes anyway... I actually think this song is BETTER than anything on 'Magical Mystery Tour'
