We were working secretly   For the military   Our experiment in sound   Was nearly ready to begin      We only know in theory what we are doing   Music made for pleasure   Music made to thrill   It was music we were making here until      They told us, all they wanted   Was a sound that could kill someone   From a distance, so we go ahead   And the meters are over in the red   It's a mistake in the making      From the painful cries of mothers   To the terrifying scream   We recorded it and put it into our machine      Then they told us, all they wanted   Was a sound that could kill someone   From a distance, so we go ahead   And the meters are over in the red   It's a mistake in the making      It could feel like falling in love   It could feel so bad   But it could feel so good   It could sing you to sleep      I'll bet my mum's gonna give me   A little toy instrument   But that dream is your enemy      We won't be there to be blamed   We won't be there to snitch   I just pray that someone there   Can hit the switch      But they told us, all they wanted   Was a sound that could kill someone   From a distance, so we go ahead   And the meters are over in the red   It's a mistake we've made      And the public are warned to stay off
