Disclaimer: I don't own Les Miserables or BTTF. If someone feels that these lyrics are too close to the original, just tell me, and I will take this down. And yes, I know that these lyrics don't fit the meter, but I don't care.
Oh Great Scott, hear my prayer
In my need, you have always been there
He is young, he's afraid
Let him rest, Einstein-blessed.
Bring him back
To his time
Eighty-five.
He's like the son I might have known
If genetics had granted me a son
The DeLorean glides through all time
How fast it flies, on and on
And I am old, and will be killed by Libyans...
Bring him peace, bring him joy
He is young, he hasn't even been born yet
You can take, you can give
Let him be, let him exist
If I dissolve
Let me dissolve
Let him exist
Bring him back to
The future...
