I guess in part it's because he's done it in live recordings such as Anthology. So we know overall what he can still do, and still does live. That's a big part if the reason I'd love something like this for Illusion, it sounds amazing with his current voice
I like most of them, but Andy Hull on SATS feels completed wasted just singing harmony and the tiny features on the last chorus. I was hoping he'd have some solo lines or something more noticeable.
