Steve's Raspy Voice ?

I've been listening to a few interviews of Steve, and one thing that strikes me is the raspy, airness, etc, of his voice over the years. The "pitch" of his voice doesn't sound as drastically changed as much as the raspiness. I realize his voice changed somewhat before TBF, but it really seems to have changed alot the past decade. So there could be other reasons why he isn't jumping on the come back band wagon.
Symptoms of vocal nodes: "Here are symptoms that are warning signs of nodes or polyps: Auditory Signs: acute or chronic hoarseness; reduced vocal range; inability to sing at length; recurring laryngitis; a tonal change from a clear voice to one that's breathy, raspy, squeaky, foggy or rough; and the inability to project clearly."
I'm not saying he has vocal nodes or polyps, but if he does.....we know from the past how much he hates surgery. And who blames him!

In this video in 2005, his pitch seems the same and notice his voice is much less raspy. Very clear, etc.

Sings "Dont Stop" with the White Sox. (Very much as sign that something is amiss.)

2006 Meet and greet with fans. Voice sounds very raspy. Also shocked to see a pudgy looking Steve! The face was rounded, he looked short, somewhat fat, etc.

In this (2007?) Ray foley interview the voice sounds raspy, you can hear it in the laughter the most.
