Speed of sound

Am i but a coward walking down the yellow brick road
Where's my megaphone
Am i but a scare-a-crow running from the seed that i've sown
Where's my megaphone
Truth moves at the speed of sound
Am i but a mirror flattering the fairest of them all
Where's my megaphone
Am i but a princess wearing a disguise to the ball
Where's my megaphone
Truth moves at the speed of sound
