There was, and maybe still is, a video....
Shortly before the French end-of-service, a small group of French enthusiasts set out in a boat (fishing boat I think) to waypoint 'TESGO' in the Channel, to hear and capture the supersonic bang one more time (TESGO is already beyond the supersonic accel point).
They brought back a video which has become a classic, with both Concorde and a contrail overhead and a recording of the supersonic bang.
A quick search on the net for "TESGO" or "Operation TESGO" didn't produce anything, but I will make some enquiries.
