Nostalgic Melody

Hello everyone. Ever hear a piece of a tune and have it haunt your memories for days on end because it’s stuck in your mind and you don’t know what it is? That’s about where I’m at. This time though, I was able to track down the original tune!
This particular tune instantly sent my mind back in time. I can’t remember anything specific, but I do remember the feeling. It’s the feeling of sitting on your front porch in the shade on a hot day, listening to the wind and just relaxing and feeling blissfully free from all worries… A wonderful feeling!
You’re probably wondering, “what tune?” It’s one that isn’t too old, but obscure enough that youngsters won’t recognize it. It’s called “Rainbow Connection”, sung by Kermit the Frog. A simple tune that drags me into the days I’ve long since forgotten. I hope everyone finds a tune that does this to them!

You might also be wishing for the answer to Riddle #5. The answer is “Clue.” it might seem obscure, but you gotta do a little research. The minotaur and string is a big hint.
