Oh how I loved them! Poor Push. We enjoyed him so much but there were parents who would stand watching as their kids ran up and kicked and pounded on him.
Although it's disguised as a fun little show, there's a ton of technical work going on there! It's really impressive to see how clean (no pun intended) the whole thing is, when performed on everyday objects. It sort of makes me wonder how good this group would be on real drums! I didn't realize that they had been gone from DL since 2009. I think there's still a group in Epcot under a different name (Jammitors?) and their routine is plenty fun, but it's nowhere near as technical (or clean) as this, nor the same level of energy
I believe I was there when they made their first appearance - Disneyland's birthday in 1995. Three guys pushing around a trashcans and we wondered what was going on since they were the circular kind which DL doesn't otherwise use. So we followed them a bit and saw them perform.
