Richie always puts a Blues dynamic to any song he sings. That is simply his style, it's where his musical heart lies.

Songs like "Wanted Dead or Alive" and "I'll Be There For You" work well with that inflection.

I have seen both Richie and Jon perform "Wanted" during their respective solo tours, Richie's version is always bluesy. Jon's version is the more traditional BJ style. As individuals, this is who they are.
