the high class stuff

[Paul McCartney:]
I was always frightened of classical music. And I never wanted to listen to it.

A taxi driver the other day had some sheet music of a Mozart thing,

And I said, "What's that?" You know, and he said

"Oh, hoh." "Oh well, that's the high-class stuff. You won't like that." He said

"No no, you won't like that." I said

"Well, what is it? ', you know. He said "Oh no, you won't like it. You know, it's high-class, that." And uh, that kind of way I always used to think of it. I used to think "Well you know, that's very clever, all that stuff." And it isn't! You know, it's just exactly what's going on in pop at the moment.

Pop music is the classical music of now.
