Next to none of them are.

Also, on that Ammons thing, the little "The Master of the Tenor Sax" thing on the label strikes me as an indicator of just how truly popular Jug was once upon a time. Bet Prestige never put anything like that on a Rollins or Trane label. It's kinda touching really, because Ammons had a HUGE following, especially in the 50s, but the "real" jazz world hardly noticed. But seemingly insignificant things like a few words on a label help keep the truth alive.
