Even the bad boy blues rockin' Rolling Stones weren't safe from the psychedelic bug that spread through the 1960's.  They later realized it really wasn't them, which makes some of their more "colorful" 60's nuggets all the more interesting.  "Experiments" Keith once called them.  It's all about rainbows today man if you can dig that.  Fire up some patchouli incense and tune in around 5:20!
