"The Key" is an original song performed by The Chipmunks in The Chipmunks episode Wings Over Siesta Grande and has yet to be released as part of an Alvin and the Chipmunks album.
Lyrics
The Chipmunks:
If you find the key
You will surely see
The entrance to the city
That's been lost for centuries
Hidden underground
Hoping for the sound
Of voices raising song
A city waiting to be found
The key (i-i-i)
The key (i-i-i)
Out here in the jungle
Unlock the mysteries (Areba!)
The key (i-i-i)
The key (i-i-i)
Filthy rich is what we're gonna be
Can you take the dare?
You had best beware
Traps are set to catch you
Better watch your step in there
The key (i-i-i)
The key (i-i-i)
Thanks to archaeology
Filthy rich is what we're gonna be
