I can't remember the post but it's probably gonna be either a nighttime parade or a dayttime parade, not both. And we definietly need the nighttime way more then the daytime. MSEP was created 44 years ago for Disneyland.
It's showings have been the following:
It's originial debut in DL: June 1972 - November 1996
It was shipped to WDW in 1999 as a limited engagement, and it ran until April 1, 2001. Then SpectroMagic came back.
The original intentions were to bring it back to DL, however due to low attednance at DCA, TDA decided to bring it to DCA as a celebration of the parks first summer. It ran in DCA from 2001 - 2010, where it was then shipped back to WDW. It was intended to just be at MK for the summer but has since then ran from 2010 till present day. MK had an exact copy of the parade that ran from 1977 - 1991, I'm assuming those floats are long gone. The original parade and the one that is currently running at Magic Kingdom is 44 years old. The Tinker Bell float is new and was added in 2008, and it also says that the Snow White & Pinnocchio floats were removed from the parade but did return in 2009, which are apparently new floats. *Most of this info is from Wikipedia, which I know isn't always the most reliable but when it comes to Disney related stuff it's normally pretty accurate*
