Roger. Great first post!. I too have been lucky enough to 'flight-deck' Concorde as a passenger, tho' not for the landing. {Did that as a pax in a Trident, amongst others!] I still have the video that I took!. Like you, I was interested in the flying of it, and asked questions, but didn't have the same luck as you with the jump seat.
I recently flew Heathrow to Kuala Lumpur in an A.380, and whilst driving from Croydon to Heathrow, went along the road at the side of BA Engineering, and there, looking beautiful in the sun, was 'my' Concorde, G-BOAB. Happy memories!. There was, I believe, the occasional rudder skin loss on a couple of Concordes, and vibration was experienced if I remember correctly.
