I really wonder how they could even do fly pasts at air shows.
The only technical reason (technical not economical) Concorde doesn't fly anymore is because the type certificate, aka the airworthiness of the aircraft, was surrendered by Airbus, hence grounding all the fleet and making it unlawful to fly it.
So to fly it, they would need that to be reinstated.
For the Avro Vulcan, they went through a different aerospace company for that.
I'd love to be wrong, but I doubt Airbus would let anyone fly one of its Concorde...
As far as I'm aware, XH558 flew on a Permit to Fly from the CAA, hence why it never left the UK. Note that being on a Permit to Fly restricts it to VFR.
