"That's Entertainment" script, Scene K

This scene was "shot December 15, 1981," I'm guessing to accommodate McKean's Spinal Tap schedule, although this date is one week before the date of the script.  The scene was about four pages in the script.

The boys' introduction of the song is similar to what aired, but in the script, Squiggy says, "Good word" to Lenny's use of "distinguishments," and then Lenny says, "Thank you," while there's an almost flirty feeling to Lenny's "I knew you would" in the episode.  And there's no "Let's feel good" cue to the band, it just goes right into the lyrics.  (I'm going to assume that "hicked up pants" was a typo that Lander corrected.)

When the boys get professorial about the history of music, Chuck Berry being inaccurately ten years old in October 1941 isn't the only thing Squiggy marvels over in the script:

SQUIGGY

Elvis was five!

LENNY
Squig, relax...

SQUIGGY

John Lennon was blowing out his first birthday candle!

LENNY

He gets a little excited over the scope of this thing.

SQUIGGY

But the point is, it don't matter whether you call it stone-age rock and roll or dixieland or an overbite...

LENNY

Or just "man's inhumanity to peace and quiet."

SQUIGGY

It's here for the fun of it so can the chatter and...

They go back to the song.  Note that Elvis was six, but John Lennon (who had been killed just over a year before this scene was filmed) was indeed born in October 1940.  As with so much of this episode, the dialogue was trimmed to make things smoother and snappier, but I like some of the turns of phrase here.  (I guess Spooky Tooth would count as a band in the "overbite" genre.  Cue the hipster skeleton drummer doing a rimshot.)

Towards the end of the scene, we get "intense jamming.  Police arrive and arrest the band."  The way this plays out is much funnier than the description of course.
