Aragorn steps up to the microphone and starts to sing, with Legolas as his backup:

Elrohir’s sister has got it goin’ on
Elrohir’s sister has got it goin’ on…

Elrohir, can I come over after I find Frodo Baggins? (Frodo Baggins)
We can hang around by the streams (hang by the streams)
Did your sister get back from her errand for Elrond? (errand for Elrond)
Is she there, or is she trying to give me the slip? (give me the slip)

You know, I’m not the little boy that I used to be
I’m all grown up now, Elrohir can’t you see

Elrohir’s sister has got it goin’ on
She’s all I want and I’ve waited for so long
Elrohir, can’t you see, you’re sister’s the elf for me
I know it might be wrong but I’m in love with Elrohir’s sister

Elrohir’s sister has got it goin’ on…

Elrohir, do you remember when I sang of Lúthien? (sang of Lúthien)
Your sister came out with her white lace dress on (lace dress on)
I could tell she liked me from the way she stared
And the way she said, “You must be that guy my dad calls Estel!”

And I know that you think it’s just a fantasy
But since your mom sailed over, your sister could use a king like me

Elrohir’s sister has got it goin’ on
She’s all I want and I’ve waited for so long
Elrohir, can’t you see, you’re sister’s the elf for me
I know it might be wrong but I’m in love with Elrohir’s sister
