While Spanish-sounding, the original song title (and chorus line) "Eviva España" does not make sense in Spanish.

The phrase "Que viva España" translates to "Long live Spain", and is probably the meaning that the (non-Spanish-speaking) authors were aiming for.

It is not known whether the misspelling was a mistake (such as confusion with the Italian exclamation evviva, also meaning "long live..."), or just intended for alliteration.

They opted to rename the song "Y Viva España", meaning "And Long Live Spain"—thereby keeping the phrasing of the chorus while having it make sense.
