And before you ask, no, this has nothing to do with the 80s-and-90s video series that eventually made its way to PBS. This is just a song from the Blue's Clues live show The Most Spectacular Place. It was also sung by the Blue's Room gang in "Skidoo Adventure" and the song from "100th Episode Celebration" is sung to the tune of it.
Announcer (speaking): And now it's time for Kid Songs with The Kids, the part of the show where the Hills of Sprout kids come out and sing a kid song. Today, the kids are in the You and Me Tree, ready to sing a song about ... well, home.
Easton: The most spectacular place I've ever known
Is my home sweet home
Star: It's where you sleep there
Banjo: And where you wake up
All: Home is where you play every day
Noodle: Home is where we draw
Banjo: Home is where there's music
Star: Home is where your family stays
All: The most spectacular place I’ve ever known
Is my home sweet home
Announcer (speaking): This has been Kid Songs with Kids. Tune in next time to hear Star say...
Star (speaking): Now I'm confused, is this song called "Home Sweet Home" or "The Most Spectacular Place?"
