Bill,
When I saw Tommy here in Adelaide late last June, at one point in his show, he said "I'm now going to play unplugged".
After a few ironic laughs from the audience, he unplugged his acoustic from his sound system, removed the rubber disc feedback buster thingo from the sound hole, and sat down in front of a microphone, then he played Duke Ellington's "C-Jam Blues", and "Nuages" and "Tears", both being Django tunes- this for me was the best part of his show that night- pure straight incredible guitar playing- with no effects or tricks.
That particular show had been postponed from the previous week, because Tommy has a congenital heart problem which gave him a scare and an emergency trip to hospital on the originally scheduled night of the concert.
If you check out his gig list on his website, he's working himself like mad- let's hope he looks after his health and takes some rest soon.
