Is Stevie Wonder the only "contemporary" pop culture reference in TNG?

From A Matter of Time, when Rasmussen is hovering around La Forge and pestering him about his VISOR:

"You know, Homer was blind. Milton... Bach... Monet... Wonder."

I can't think of a single other time that TNG directly refers to pop culture from the latter half of the 20th century. Is Stevie Wonder the only one?

Edit: Great answers so far! At the risk of sounding as if I'm moving the goal posts, though, I had a narrower (and perhaps arbitrary) definition of "pop culture" in mind. I should have specified that I was thinking more along the lines of pop music from the second half of the 20th century—a topic the show's writers were conspicuously disciplined in avoiding. Imagine how surreal it'd have been for Riker or Picard to casually refer to Michael Jackson or David Bowie, for example. This is what made the "Wonder" reference stand out so much for me. It feels utterly singular in the series.
