"Since I am quite obviously the old timer of this group, I thought I'd dust off a classic. Any of you kids ever heard of Ol' Blue Eyes?" John asks. Elliot grins at him. "Not you, Stabler," John deadpans. "Sinatra," he grins at Casey as the song begins.

I've got you under my skin.
I've got you deep in the heart of me.
So deep in my heart that you're really a part of me.
I've got you under my skin.
I'd tried so not to give in.
I said to myself: this affair never will go so well.
But why should I try to resist when, baby, I know so well
I've got you under my skin?

Casey is blushing and grinning, and I'm thinking about the fedora that John always wears in the winter. He is sort of Sinatra-esque.

I'd sacrifice anything come what might
For the sake of havin' you near
In spite of a warnin' voice that comes in the night
And repeats, repeats in my ear:
Don't you know, little fool, you never can win?
Use your mentality, wake up to reality.
But each time that I do just the thought of you
Makes me stop before I begin
'Cause I've got you under my skin.

As the few bars of music wash by, John does the same little dance step that the boys did when they sang "My Girl."

I turn to Elliot. "Did you practice that, you weirdo?" I tease.

"Hey. We had couches to earn our way off of," he defends.

I roll my eyes. "I love you so much," I say.

"I know, honey. You should. I'm singing karaoke. And dancing," he adds.

I place a chaste kiss on his lips. "And for your efforts, you shall be rewarded," I promise.

I would sacrifice anything come what might
For the sake of havin' you near
In spite of the warning voice that comes in the night
And repeats - how it yells in my ear:
Don't you know, little fool, you never can win?
Why not use your mentality - step up, wake up to reality?
But each time I do just the thought of you
Makes me stop just before I begin
'Cause I've got you under my skin.
Yes, I've got you under my skin.

John takes a little bow at the end of the song and heads offstage.

"That was great, baby," Casey exclaims, kissing him lightly.

"Thanks, Case," he says.

"Sinatra. Now that was one cool cat," Henry says with a grin.

"Pretty classic, partner. Nice work," Fin says.

"Thanks guys. What'd you think, Ol' Blue Eyes?" he asks Elliot.

"Not bad, John. Not bad at all," Elliot says with a chuckle.
