It is possible that the whole after-concert was recorded.
Just imagine how well this whole release could look:
1) Blu ray with docu and the after concert as a bonus
2) Separate CD with the final night of the tour including White Christmas
3) CD with alternate versions
4) Album on CD
5) Maybe vinyl
Would've been awesome. Personally, I'd love to see a performance of See What A Fool I've been, but QPL meanwhile...
That said, it's nice to know that footage DOES exist.
