Lyrics
It is wrong for me to ask questions?
Is it wrong to seek the truth?
I just can't blindly accept their version.
I can't base my logic on proof.
Almost all the evidence points one way,
But I'm like Charlie Sheen and Gloria Estefan:
I need to know what really happened
On 9/11-leven-leven-leven-leven.
What really happened
On 9/11?
