Please help me decipher this Zig Zag People lyric YSI

Please help me decipher this lyric from "Peel It Off Your Face" from The Zig Zag People: Take Bubble Gum Music Underground (Decca 1969). Very brief background - it's an album of bubblegum songs ("Indian Giver," "Simon Says," etc.) done in a bluesy psych-rock style. "Peel It Off Your Face" is an original about bubblegum music. I have most of the lyrics:

Bubblegum will leave its mark on you
Kasenetz & Katz, Bo Gentry too
But it's not so hard to peel it off your face

Take out some insurance on your soul
When you listen to that bubblegum rock and roll
But it's not so hard to peel it off your face

1650 1650
You've been 1650-ized (calling out track numbers football-style)
That's how many tracks it takes to make a song
THIS IS THE LINE I'M MISSING

Key of C is mainly what we play
Cuz sharps and flats only tend to get in the way
And our guitars just ain't programmed that way

And then there's some stuff about reverb and gimmicks. The missing line sounds like "That doesn't mean a thang but (a?) two minutes long."

Help? Thanx!

Here's the track:
