Watch as Paradise Bay comes to life with the symphonic sounds of the Main Street Electrical Parade’s Baroque Hoedown. It appears that the show can do a different set of songs when Maestro Goofy is unavailable to conduct the fountains.
The music is from an album recored by The Cincinnati Pops called Disney Spectacular.
Isn't this "Baroque Hoedown" (MSEP Theme) from the Disney's Magical Express loop?
