#9 Dream by John Lennon. Guess how high this song charted in the United States? That's correct, at position #9. #9 was a special number to Lennon because it always seemed to be hitting him over the head; for example, many of the most important dates in his life always seemed to fall on the 9th of a month.
One other thought: If you'd ever really like to get the phrase "#9" branded into your mind forever (I know, just the sort of thing that you have probably often desired), then check out Lennon's Revolution No. 9 from the Beatles' White Album. That song's lyrics go as follows: "Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number ... Number Nine ... Number Nine ... Number Nine ..." AND THEN later, just for good measure, the lyrics continue as follows: "Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number Nine ... Number ... Number Nine ... Number Nine ... Number Nine ..." You have to love John Lennon.
