Some of my students have told me that they want to see me when I'm practicing and haven't edited out my mistakes. It's embarrassing for me to watch my mistakes. We all have things to work on. 
Here are a couple of takes of When I'm Sixty Four. The first take I just picked up my guitar and didn't even tune it. It was in Eb tuning and I didn't realize it. 
The second take is in standard tuning. I make mistakes in both of these takes but back up and keep going. I'll make a cover out of one of these takes, edit out the mistakes, etc.
Let me know if you like to see me practicing. If you can learn something that is great.
Thanks for your support.
