I don't have a problem with people thinking someone else should have sung TITTL but I don't understand why they think it should have been sung high just because Randy sang it that way. As I have said on numerous occasions Glenn put his own spin on it & didn't try to be a clone (because he couldn't).
I actually think Glenn could have sung TLR, but never mind. But as for VOL, it's the lyrics thing again, Henley wrote the lyrics. Therefore Henley sang it. It's a totally Henley lyric which Felder with his limited vocal abilities could not have interpreted well enough. I know SS has heard Felder's version, but as I never will hear it I can't comment on it any further.
