I had a little telephone chat with Art earlier today. He sounded a tad weary but in good spirits. We kept it short but I think he welcomed the call. He said he was thinking he might could still have some fun with a banjo and recalled Fleming Brown telling him that playing banjo is frequently a "hit-or-miss thing." He also recalled Jim Brewer figuring out how to play without a finger that had been badly damaged. He said he was having trouble sometimes finding the right words, but he sounded still pretty sharp to me.
