Quickly: Our lead guitarist and vocalist is injured. I had to find a sub as not to cancel a gig. I hired a solo/singer songwriter type who actually plays mostly covers, alone on stage. We practiced two times, and I took notes. Well, on stage we played "okay" and even had some "moments". However, we were off at times, and he would play songs that we hadn't practiced. So, I had to "use my ears", watch his hands, and BS my way through songs. People and the venue owner were okay with it. I am very particular, and I am lucky enough to play with some tight bands. It has been a long time since I had to fly without a net, and not in a "jazz" way. Question: Has anyone had the low self-steem moment of not being part of a "perfect" performance. Did you beat yourself up, or can you move on? I replay the moments for days afterwards, even though people say, "you guys sounded good!"
