Seems like some sort of green screen effect on the second pic, but still a bit too abstract to fathom, probably a statue of some sort. I do wonder if this is something even known about in any list of possibles we have
Ok I think I will have a guess at the routine. I will write the name in the same colour as the background so you will only see it if you highlight it with your mouse. This is not to spoil the fun for others.
Don't Let The Sun Go Down On Me. Explanation: If you count all the letters of the routine, there are 23. 14 % of 23 is roughly 3. The picture shows a Don - these are the 3 letters which begin the name of the routine.
I have it somewhere in the back of my head that Sue dances a solo spot in that routine. Hopefully thats the 14% thats survived.
I think you may be right about the solo.
I'm guessing the 14% suits the clue as the routines were usually shorter than the record so it is extremely unlikely that the actual length is known. The song is 5m 35s long, I'd take 14% of that! (Wikipedia)
To be honest I'd take a picture and proof of what they were dancing to for the missing routines, anything more than that is now a massive bonus.
