Firstly, I had to do it. The risk of a song being parodied is directly proportional to the emotional seriousness of the original. It's why we make jokes about death, injury, and in-laws.

Secondly, I don't think anybody's ever gonna sing it, but it might be amusing to see once.

ISLIP, LONG ISLAND

Islip Long Island, 19 and 60. My dear loving daughter Estelle:
I hope that this small, insignificant letter finds you happy and well.
I hope San Francisco is all that you dreamed of, although it's a long way from here.
I hope that you watch out for bad boys and beatniks. There's a lot in this world you should fear.
Your brother's moved close to his girlfriend, so he says, but I fear they are living in sin.
Please don't concern yourself. I'm doing splendid but I can't wait to see you again.

Islip Long Island, 19 and 70. My dear loving daughter Estelle:
Say hi to Moondog. He looks like a nice boy, but with all that hair I can't tell.
Does his mother know that he has hair like a hippy? I hope you have checked him for lice.
Oh well, never mind. I'm just being a mother. I'm sure that he's really quite nice.
And the wife of your brother, I don't think she likes me. She wants him to move to Bayonne.
Your room is exactly the same way you left it. Anytime you want, you could move home.

Islip, Long Island, 19 and 80. Dear daughter Estelle and son John:
I'm sorry to give you the very sad news that your father, that bastard, is gone.
He moved out last weekend to live with some floozy. She's skinny and has curly blond hair.
I'm a shame he decided to trade you poor mother for a pretty young head filled with air.
But please, not to worry. I'm sure I'll recover. At least that's what my doctor has said,
But I hope you're still planning to move back to Islip Before your dear mother is dead.

Islip, Long Island, 19 and 90. My dear loving daughter Estelle:
I'll be fifty-one this coming Sunday and my colon is giving me hell.
I just mentioned my birthday in case you'd forgotten. I know you're too busy to call.
Thanks for the pictures. It's the only reason I know what the kids look like at all.
Except for the clothes from the Salvation Army, they're lovely young women and men.
Are you thinking you might bring them here for a visit? It would be nice to see you again.

Islip, Long Island, 19 and 92. This is your dear brother John.
I'm sorry that I didn't write sooner to tell you that mother has moved on.
She was living with some guy she met in college. I think he is just thirty three.
She sold the house and closed all the accounts and they're off on a traveling spree.
And she sent us a letter from a country in Europe, and some photos they took on a cruise.
If you ask me, she has lost it completely and the young man's affection's a ruse.
And it's funny the way she kept talking about you. She said something to you at the end.
She said, "Tell Estelle you get one chance at life. Maybe someday I'll see her again."^^
