I heard a song on the radio today that I haven't heard in a while, Led Zeppelin's, "Since I've Been Loving You".  Here is a link to the studio recording of that song I found on the Internet.  Take a listen to it, preferably with headphones on and kind of loud. I put the link to the recording at the bottom of this entry (for some reason it wouldn't let me paste it up here). Did you listen to it closely, I mean really closely?  Did you hear the faint squeaking in the background?  It sounds like a light/faint bird chirping in the background that starts with the second beat after the drums start and continues thru the song but is only audible during the quieter times of the song.  Probably Bonzo's kick drum pedal that just needed a little oil. 

I remember the first time I had noticed that "squeak".  I was probably 16 or 17 years old lying on my parents living room floor listening to Zeppelin with the headphones on loud.  The second I heard that squeak for the first time I sat right up and though "holy sh*t", I had never noticed that squeak before, and for some odd reason I was a little excited about it.

I later had mentioned that newly noticed "squeak" to a few of my other die-hard Zep fan friends of mine.  All who looked at me like I was crazy at the time.  Some even while we where listening to the song and I was going "there, did you hear it that time, it was right there"?  None of them ever heard the "squeak". 

How did that "squeak" get there, didn't anyone in the recording studio, or was the magic that was happening right in front of them just too great to stop at the time.  I guess it really doesn't matter the reason, it's there and I still hear it to this day.  Did you hear it? 

I guess what that "squeak" represents to me is the human side of life and music and no one, no matter who they are is ever really all perfect.
