(Rudolf Friml / Herbert Stothart / Robert Wright / George Forrest)      There's a song in the air   But the fair senorita doesn't seem to care   For the song in the air      Oh, I'll sing to the mule   If you're sure she won't think that I am just a fool   Serenading a mule      Amigo mio, does she not have a dainty bray?   She listens carefully to each little tune you play   La bella senorita   Si, si, mi muchachito   She'd love to play it too if only she knew the way   But try as she may   In her voice there's a flaw   And all that the lady can say      There's a light in her eye   Though she may try to hide it   She cannot deny   There's a light in her eye      Senorita, donkey's feet are   Not so fleet as a mosquito   But so sweet like my chiquita   You're the one for me      He's a mule, what a mule   But all that my darling can say   Hee-haw-w-w-w-w-w-w-w-w-w      In his face is a dream   Like an angel that I saw   But all that my darling can say   Is hee-haw      He can try as he may    In his voice there is a flaw   But all that my handsome can say   Is hee-haw-w-w-w-w-w-w-w-w-w      There's a light in his eye   Though he may try to hide it   He cannot deny   There's a light in his eye      There's a song in the air   But the senor doesn't care   And I love him so   Even though he's just a mule   I get a great big kick from that Senor mule   Singing the donkey serenade
