Okay, it seems as though there hasn't been a lot of activity in here recently, but I wanted to point something out. I have the first season of Fraggle Rock on DVD, and I've watched Down At Fraggle Rock the behind-the-scenes look in the extras quite a few times to know some of the lyrics of the song are off. What I definitely heard was:
You're as crazy as your Uncle Matt!
Around the universe/
Exploring every mile/
My mind often turns back to Fraggle Rock/
I'm marching on with a smile
All around the world/
There is no better place (pushin and a-shovin' when we only need some lovin')/
You're lucky you're living in Fraggle Rock/
Who needs to be in Outer Space?
That's only parts of the song I could make out. Honestly, the whole "thunder and a-lightnin' and a fuedin' and a-fightin'" debate, I really can't say but it sounds like that's what the Fraggles are saying but it doesn't sound right.
I found this on YouTube. Hopefully this'll help:
