This song is the one that Princess Shera and Meme sang in the second movie. The one for the musical cage, yeah.

Kaze ga wataru, tsuki no sabaku wo
Anata ga tabi shita harukana sunaoka
Futari de itsuka koeteikitai
Kin'iro no kaze ga fuki,
Kin'iro no fue ga, ai wo utau

Kaze ga naita, yoru no sabaku de
Anata ga nokoshita, chikai no kotoba
Futari de yume wo, ashita wo tsukurou
Kin'iro no kaze ga fuki,
Kin'iro no fue ga, ai wo utau

Kaze ga hikaru, kin no sabaku de
Anata ga miageta ookina ginga
Futari de ai no inori sasageru
Kin'iro no kaze ga fuki,
Kin'iro no fue ga, ai wo utau

Lyric from Kykyosama

This is the traduction. Is fan-made, but it's accurate to the real meaning:

Title: Golden Wing

The wind blows in the lunar desert,
far-off dune from where you cross,
where I love to go with you someday.
The golden wind blows,
the golden flute sings the love.

The wind cried in the nocturnal desert
where you leave promises about how
tomorrow our dream we will create.
The golden wind blows,
the golden flute sings the love.

The wind shines in the metalic desert,
where you was looking that big Milk Way,
offering a prayer for our love.
The golden wind blows,
the golden flute sings the love.
