Here is the freestyle and full retirement ceremony from FEI TV the the FEI have put on youtube. It was lovely, it is likely that we may never see his like again. 
Great stifles on that horse.
OP - How neat that you got to meet Valegro in 2012 and see him being ridden so close to where you were standing! Thanks for sharing your story! He and Charlotte are the best of the best, and I adore Carl as well. It’s Blueberry’s happy attitude and Charlotte’s genuine love for the horse that shine through to even non-horse people.
Lovely story! So happy to see him retire on top and happy!
