O come, O come, El Ni-i-i-i-ño*Per Wikipedia's** insanely thorough article about "O Come O Come Emmanuel," John Mason Neale wrote the familiar English lyrics for this song (adapting the Latin "Veni Veni Emmanuel").
And drop your load of ra-a-ain and snow
We parch in thirst and wo-o-rry here
Until your clouds and sto-o-orms appear
Rejoice! Rejoice! El Ni-i-i-i-ño
Shall come to make the ri-i-i-vers flow.
