I thought it was ok, but it looked as though it could have done with another full rehearsal or two (I appreciate that the Closing Ceremony team get minimal rehearsal time in the stadium compared to the Opening Ceremony)
Didn't quite get why we had to see Emilie Sande (who I find Ok but not fantastic) twice though, nor did I understand why we had to hear the same songs (Blur, Madness One Direction) while the Athletes entered the stadium, when we had only heard the performances minutes earlier. It was like the DJ left the CD on while he went to the loo!
got better as it went on though, and credit to Gary Barlow for his professionalism in turning up to do his job and not let his bandmates down after such an awful week.
