Como una promesa, eres tú, eres tú.
Como una mañana de verano.
Como una sonrisa, eres tú, eres tú.
Ah sí, ah sí, eres tú.
Translation (not sure how accurate):
Like a promise, you are, you are.
Like a summer morning.
Like a sunrise, you are, you are,
Ah yes, ah yes, that’s how you are.
“sonrisa” LOOKS like sunrise that’s for sure, but means smile.
But in the song both are nice anyway, so why not? 
Catch a falling star and put it in your pocket -
Never let it fade away.
Catch a falling star and put it in your pocket -
Save it for a rainy day.
[Played off of “Como” :)]

Ah weem bo wep, ah weem bo wep, ah weem bo wep,
In the jungle, the mighty jungle,
The lion sleeps tonight…
Hakuna Matata!
What a wonderful phrase
Hakuna Matata!
Ain’t no passing craze
It means no worries
For the rest of your days
It’s our problem-free philosophy
Hakuna Matata!
(spoken) Yes! I mean “No!”
(singing) Just like a busy bee
Each new philosophy
Can fly from tree to tree
And keep me moving!
When life’s a dizzy maze
On alterating days
I choose a different phrase!
Thanks for the help. My Spanish is poor to begin with, and it has only gotten worse as time goes by. I did the best I could, and I’m glad to know that both would be suitable for the sentiment. 
Continuing …
They took all the trees,
And put 'em in a tree museum.
And they charged the people,
A dollar and a half to seem 'em.
I’m so afraid that the plans we made underneath those moonlit skies
Will fade away and you’re bound to stray if the stars get in your eyes
So, don’t sit under the apple tree with anyone else but me
Every little breeze seems to whisper Louise
Birds in the trees twitter Louise
Each little rose tells me it knows I love you
Love you
You cry and moan and say it will work out
But honey child I’ve got my doubts
You can’t see the forest for the trees
There’ll be lots of time and wine
Red yellow honey, sassafras and moonshine
Red yellow honey
Sassafras and moonshine (moonshine)
Stoned soul, stoned soul
Surry down to a stoned soul picnic
Surry down to a stoned soul picnic
Chicks and ducks and geese better scurry,
When I take you out in the surrey,
When I take you out in the surrey,
With the fringe on the top…
You’re the Nile, you’re the Tower of Pisa,
You’re the smile, on the Mona Lisa.
I’m a worthless check, a total wreck, a flop,
But if, Baby, I’m the bottom,
You’re the top!
See the pyramids along the Nile
Watch the sun rise on a tropic isle
Just remember, darling, all the while
You belong to me
Just call me Cleopatra, everybody,
'Cause I’m the queen of denial…
Don’t you draw the Queen of Diamonds, boy
She’ll beat you if she’s able
You know the Queen of Hearts is always your best bet
She’s a Killer Queen
Gunpowder, gelatin
Dynamite with a laser beam
Guaranteed to blow your mind
Anytime
