WF - do you happen to know whether Eddie Gregious ever played a 12-string lyre? You know, like Leadbellious.

I believe he did Will, but not like Leadbellious (not to be confused with Leadbillious or Leadbellows), who invariably played bottleneck. You mentioned Gregious' habit of playing with his teeth - you may be interested to know that he actually wrote "Bite my Lyre" on the twelve-string. Scholars tend to overlook his non-blues compositions, but in fact he wrote a right load of ballads.
