This might sound odd...but say what if Justin or any of the other member of the band were conceived on another night, week or month...they could have been entirely different people than they are today.

Or what if just one episode in Justin's life were different, would we have the songs we have today...

So I say its difficult to say "what if" Justin were part of the Animals, what would have become.
After hearing what the great work The Animals have done, the styles just do not mix, the would not have complemented each other like the Moody's do....and Eric Burdon was just a little bit more "out there" and eccentric than Justin was...I think leadership would have been an issue...things would have clashed.

Glad it turned out the way it did.

I will return no more, I'll take my heart and let it fly.
