I think the verse with the sheep is about his band now and how he feels it's not as solid as he'd like. But I'm only guessing. It just sounds like it because there's three of them, and he "takes their tales" and is ready to write the lyrics and sing. And Jack maybe isn't able to fully commit because of Steel Train and such, so he has to take other calls, other roles. just a thought.
