[Jojo's Bizarre Adventure] Do the Jojos/Jobros ever get worried when they hear band names?

I mean, a good portion of the names of villains are bands.

So when Woodstock happened did someone like Joseph say "OH SHIT! SANTANNA IS BACK!!!" Or really any of the pillar men to be honest, all of their bands would pop up during Joseph's life time.

What about Polnareff's face when like two years later he hears that Vanilla Ice is around and about?

Most of the villains have archetypical names which existed long before the bands, and also long before the villains. 

Like, "Santana" was a name that existed long before Joseph's time. It's just an alternate/variant form of "Santa Anna" which is a relatively common Spanish name. Tons of people and places have that name, perhaps most famously Antonio Lopez Santa Anna.

REO Speedwagon probably took him by surprise, though. That one's a bit odd.
