How are you is one of the phrase I remember from my high school Spanish. It's "Como estas?" {or "Como esta?"}.

And I believe that you're correct that "Hasta la vista" is a colloquial expression that means "Goodbye {actually, it really means something like "until I see you again".

I wonder when this "como la vista" [or something like it} rhyme became popular and whether its source was not just a colloquial Spanish expression but a recorded Spanish song.

A number of verses in contemporary children's rhymes have their origins in titles, refrains and/or lyrics of R&B songs.

Here's two of them:

We Will Rock You
we will we will rock you (small pause) we will we will rock you mud on you face a big disgrace kicking your can all over the place singing we will we will rock you down shake you up like a volcano will erupt buckle your seatbelt step on the gas were gonna kick you in your ask me once ask me twice everybody we will we will rock you (small pause) we will we will rock you
{while singing stomp one foot then the other then clap throughout the whole song}
