Good for you on the fingers technique - impressive! Yep, you'll do fine. We both know most of the audience has no idea about the intricacies of what Paul played (especially on a song like Hey Bulldog,) so as you stated, as long as the feel is right you're good to go. Don Was did great in the clip that was shared above.

Happy Thanksgiving and "Get Back" Day to you as well! I can't wait to watch it.
