One wrench in the gears is that I am not really driving yet due to the meds thing. My wife or son will be driving me and then picking me up later.
I got BCC'd on an email from him to the group. A simple, "Is Monday practice still a go??" thing. I figure at this point asking if I should bring anything might be a non-presumptuous query. If anything, I'd like to sit and play unplugged to see if I could keep up. See what my head would allow me to do and the price I pay later that night. There's not only noise, but movement to deal with.
A funny story. One of my most embarrassing moments while learning this guitar thing.
He came over to the house one time to "jam". I did not know what this meant yet. So, when I started playing rhythm to whatever song it was and when he started playing lead , I stopped. I didn't know what the heck he was doing. I thought he just wanted to play or show me the proper technique, so I stopped and let him. He got a puzzled look on his face. After a couple more times he tried to explain this jamming thing, but it didn't sink in. Getting more and more embarrassing now. I think he gave up and we did the one at a time thing. I got sick right after that, and he got busy with his band by the time I've been able to do things. We never played again. About two years later, I learned what jamming actually was by my brother-in-law. Man, talk about embarassing. I did email him and told him about my blunder from that evening and we had a good laugh.
