Possibly, the greatest moment I have ever seen and really wished I was there for!

Ok, this has nothing to do with photography, but it does capture a surreal (and totally awesome) experience in a real world settting. I have always loved musicals and ever since I was a wee little lad I wondered what it would be like if everyone just spontaneously got into a dance routine!! I always had questions like where would they rehearse? How would they know when to do it? This video lives out that dream for me in such a spetacular way and in Liverpool Street Station, London! Simply awesome.
