Japanese Bat Bomb

I work as a dental surgeon, March of 1943
 They need a way to beat the Japanese, so I stepped up
 I made up a weapon that was elementary
 But effective to a T, and I showed them
 Little leather
 With incendiary feathers
 They all agreed that it will work
 And oh, in 16 days
 My bomb will make its way
 To the shores of Nagasaki
 America the beautiful lives on.
 Lately I've been drinking,
 Feeling bad for what I've done
 To the land of the rising sun, and its daughters
 And many men and women will die from what I've made
 They will fear the bat brigade, flying over the Western waters
 We watched the fuel truck burn
 And realized that it was our turn
 To tell men how to die
 It's for the greater good
 I'm sorry to say.
 There is no other way
 America the beautiful lives on.
