In this Blabbermouth story, Don is quoted recollecting about posters on the Dokken message board, when it was active, and he singles out a poster who went by "Acorn" who apparently criticized his vocals:

I can't quite remember, but the poster who went by Acorn or The Acorn, here (because of the Ace Frehley solo reference) also occasionally posted about and mentioned seeing Dokken, right? I wonder if it's the same person...
Kind of silly that a message board poster would remain in Don's mind all this time.
In any case, I thought it was interesting.
