One thing I have noticed is that JBJ isn't as animated on stage as he once was. I watched a video of their "Slippery" concert in Sydney back in 1987 and he was running and jumping around the stage heaps and really working the fans in every song, smiling and high fiving. Yet when I watch the "Crush" concert he isn't as active and is more inclined to stay close to his mic, only breaking out in the odd song. I know he's 10 or so years older but that cheekiness/brashness has gone. Yet if you look at an old boiler like Jagger his moves are the same as what they were 30 years ago. JBJ is still the undisputed heavyweight champion of sex appeal though. Just ask my wife lol!
