The beloved SpectroMagic night time parade replaced the Main Street Electrical parade as part of Walt Disney World’s 20th anniversary celebration, and ran until 2010. This video is from February 1999.
And from December 1998, here is the holiday version of Illuminations at Epcot. While this pre-dates Reflections of Earth, fans of the holiday tag will find many familiar sequences here.
That “Let There Be Peace on Earth” tag at the end still gives me chills after all of these years! Thanks!
