Sense.

Hey there, all you middle men

Throw away your fancy clothes

And while you're out there sittin' on a fence

So get off your ass and come down here

Cause rock 'n' roll ain't no riddle man

To me it makes good, good sense

Good sense

Angus and Malcolm Young, from the poem, "Rock & Roll Ain't Noise Pollution"

Rock and roll is just rock and roll
