It was the opening of the Disneyland Paris' "Imaginations Parade".
On the corner into Main street (Castle end), a large stage was set up and a Disney official was there to open and present this brand new (& apparently very expensive) parade. He made a speech in French before officially opening it.
As the parade commenced I could hear the music slowly getting louder before the first float (with Mickey and Minnie on board) appeared infront of me, until - it suddenly halted, right in-front of the Disney official!!
The music kept going for approximately half an hour, with the dancers still dancing, during this period the crowd didn't quite understand what was going on - was this part of the show? The wheels on the underside of the float had become stuck in the tram tracks!
After a while, a small tow appeared and a gentleman stepped out and gave the first float a hitch down Main Street before returning back stage.
I am pretty sure the Disney official wasn't too impressed! Although, I was very impressed by the Cast's professionalism to carry on dancing and keeping the crowd entertained during that period of uncertainty!
Has anyone else experienced a "hiccup" with rides, parades....?
I find it freaky enough when it works
