There is no one...

[songlover]

There is no one but you and will never be. - No hay nadie pero tu no será nunca.

There is no one but you and will never be. - No hay nadie pero tú y no lo será habrá nunca.

The English version is equivalent to "there is no one but you and (there) will never be (anyone)". English allows the words in parentheses to be left out, but one must still take them into account in order to translate the original version appropriately.

It's possible that it should be "sino" instead of "pero": perhaps a native speaker will comment or make better suggestions.

No hay nadie más que tú y no lo habrá jamás.
