Flint said:1) I haven't recorded or performed in 20 years and cannot do what I used to consider basic stuff.
2) It is hard to play alone without any interaction with an audience of any kind.
3) I made several mistakes.
4) I didn't rehearse anything, just sat down and tried to quickly think of something to play. I spent most of the day setting up the recording gear and cameras rather than warming up or practicing.
