Song lyrics to The Donkey Serenade. Music by Rudolf Friml (1923). Lyrics by Chet Forrest and Bob Wright. Sung by Dean Martin and Jerry Lewis in My Friend Irma

There’s a song in the air,
But the fair senorita
Doesn’t seem to care
For the song in the air.
So I’ll sing to the mule
If you’re sure she won’t think that I am just a fool
Serenading a mule.
