I have ordered all the books listed on Amazon, and I am ordering 20 more on obsessive compulsive disorder. In the mean time I am making sure that I have vinyl, CD and digital copies of every Beatles song, sound or utterance. In mint condition. Preferably unplayed (even the digital stuff--no telling how playing them potentially degrades the code).
However, if I do break down I may listen to "Number 9" 144 times in a row (1+4+4=9. also 144 is the number of perfection, 12 X12, twelves tribes of Israel, twelve lost tribes, 144,000 to be saved at the end-times, check Revelations). It's amazing the things you start to hear after about listen no. 84 (adds up to 12, just chance, you say?)
You say. Hmmmm. There's the rub.
