Lyrics
Chorus
“You don’t know how much you have to know
In order to know how little you know
Never say or think, you know it all
Look and listen, keep mum, lay low
The fool as a rule always says, ‘I told you so’
The wise just surmise, and you’ll never hear them blow
You don’t know how much you have to know
In order to know how little you know”
