Sampling litigation was rare back in 1989, so you guys got by without much trouble on Paul's Boutique. But the album is still sold today - have you had to license all those samples retroactively?

YAUCH: Well, I think there's a statute of limitations on that stuff. If 10 years have gone by or whatever it is and there hasn't been a problem, then it's not an issue.

HOROVITZ: At least that's what we're hoping. [Laughs.] You know, I'm pretty sure we were actually the first court case that used the word sampling in it. It was in a lawsuit involving a sample of Jimmy Castor's "The Return of Leroy (Part One)" on our first album.
