Enjoyed your Edinburgh concert hugely. A real testament to the greatness of Bach. I mentioned afterwards an inspiring book about Bach which I'm guessing you know already...Evening in the Palace of Reason by James Gaines. Not sure if you get the chance to immerse yourself in the cantata repertoire! But if you don't know it, spend 10 minutes on BWV 118, a breath-taking motet that miraculously captures all that is great about humankind. What a man... What a world to have such a man in it!
