For decades, nobody had any idea what John was saying in the chorus. The booklet claimed he said "You are on the road" yet, almost everyone who listened to it thought he was saying "You are all alone". So, I came across the master tracks of Blood Sugar Sex Magik ripped from Rock Band 2. I investigated with the master vocal track paired with my expensive Sennheiser headphones, and solved the mystery. He's saying BOTH! The first time he says "You are all alone" and then "You are on the road". So there we have it. Not even the official booklet could get it perfectly right.
I also took the liberty to upload it for you all to check out.
