For many years they used to have a parade with all the cast members walking around world showcase.
The last year they did that was 1997.
In 1998 the pavillion was decorated with lots of red and white bunting and balloons and they had scottish dancing and daytime fireworks.
Over the past few years they've done less and less. I don't think they really did anything last year.
If you're there this year, please let us know if the celebration has improved. I used to be a CM there on the International Program.
July 1 is also the anniversary of Off Kilter - they debuted on July 1, 1997.
