I really wanted to post an article that was entertaining and informative (or kinda), so I decided to do the "101 Things You Didn't Know About Rock N' Roll" (I know you probably know quite a few and that they ain't all about rock but...its a catchy title!). I tried to research as much as I could, but maybe there are some things that aren't (totally) true, so corrections would be greatly appreciated.  
 
A few tidbits:  
18. Van Halen's "5150" is named after Eddie's Peavey 5150 amp, which is built exclusively for him.  
29. Black Sabbath's guitarist, Tony Iommi, lost part of two fingers in a "work accident", and it seemed the band was over. However, he managed to continue playing using a device which made his two stump fingers "longer", and tuning the guitar three steps down in order to loosen the strings and bend them more easily. His first song with his new "style" was a damn good one: "Iron Man".  
36. Malcom Young used to play the solos in AC/DC, until one day he told his brother "You do them...cuz they keep busy the hand I use for drinking!".
Excellent
ERICJ: Great list.

substrate: Sacriledge, Stevie Ray Vaughn wasn't country.
Hmmm...
Novelhead: 20. Jimi got the inspiration for "Purple Haze" after having a dream where he could walk underwater.  
 
 
I guess that's the difference between geniuses and regular types. Jimi had that dream, and he wrote one of the best rock songs ever. I had that dream, and I wet the bed.  
 
I think Van Halen's 5150 album came before the amps
