What's the Voltage William?

What’s the voltage, William?
What’s the reason I’m insane?
So long since I saw the sun
Only my face and the rain, again
Information processing
Working hard just to be free
Bitter talks and dancing fleas
Will you come to rescue me, oh please
I’m waiting for the warmth of the sun
I’m waiting for the warmth of the sun
And over and over again
I’m waiting for the warmth of the sun
I’m waiting for the end
Of winter
To linger
Under the summer sun
No winter
To linger
Under the summer sun
