Back in my party days, I did some lines with the Boquist brothers after a Son Volt show at the 40 Watt in Athens. They told me Jay smokes a little weed, but that's it. I doubt his weigh loss has anything to do with the hard stuff....
I was present for Jay's rather pedestrian show at the Bowery Ballroom last night and was stuck by how gaunt he looks. He must have dropped 30 pounds. I hope he's not doing hard drugs, although that would explain a few of the tracks from his last 2 releases...
