Aww, that day.. I remember the dance very well. It was such an amazing, heartwarming moment to see them - and all of us - celebrating their anniversary, their love. The recording of that special moment is truly a good way to say goodbye. It's a recording not just of some dance but of their wedding and all the memories they shared since then and I hope it will help his family as well to allay grief a bit.
Rest in Piece.
