Ill blow my voice out.

I know how to maintain my career, my health, and Joes passionate.

I dont think he knows how to.

I think hes out there and someones overbooking him.

Theyre doing like eight or nine shows in a row, or five in a row.

I think theyre all a little burnt.

I think they may need to look at that.

Not young anymore, yknow?

Im really concerned and worried right now that Im not getting any news, Tyler said.

Im a little bummed out, and that scares me.

I dont know what it is, but I know that nobodys talking to me.

I can only tell you that Joes my brother and I love him so much.
