Sesame Street Wishlist

I wanna listen/watch the following:

1: This rainy day song where the lyrics go "it's a rainy day, it's a rainy day, it's raining outside and we can't go out to play, why must we need the rain, anyway."

and it ends with some reasons why we need the rain...like to cause flood, spread diseases, tsunami..of course not.

2: This song where the lyrics go "is a postman a person in your neighbour, in your neighbourhood, in your neighbourhood? he's the person that you meet, when you're walking down the street, they're the people that you meet, each day!"

3: The imagination song by Ernie. "Sometimes I imagine, that I would like to be, a daring bold explorer, sailing far across the sea"

Please! Anyone?
