I'm walking on air   For I left all my blue days behind   I've learned how   And there's love, really love, on my mind      I'm the world's most happy creature   Tell me   What can worry be?   I'm crazy 'bout my baby   Baby is crazy 'bout me      Mr. Cupid was our teacher   That's the reason we agree   I'm crazy 'bout my baby   Baby is crazy 'bout me      Papa get that book out   Ready in your hand   Keep a steady look out   So you can understand      It's an A-one combination   With a perfect he and she   I'm crazy 'bout my baby   Baby is crazy 'bout me
