Learn from Songs · Unit 9: Conditionals · B1
One of the coolest songs ever recorded, about a love so hot it gives you a fever: the zero conditional for things that always happen (When you kiss me, I get a fever; if you heat water, it boils), if or when, and the imperative in conditionals (If you feel ill, stay in bed), with Philo, Sophia, Marcos and Demetria.

Tonight’s song has only a double bass, finger clicks and a voice. And yet it is one of the most famous recordings in the world.

Only finger clicks?

And it’s about a fever: not an illness, but love. Every time he holds her, she gets a fever. Listen for “when” and “if”.

When it always happens: the zero conditional.
Los Angeles, 1958
“Fever” was first recorded in 1956 by the young R&B singer Little Willie John, and it was a hit. It was written by Eddie Cooley and “John Davenport”, a false name used by the songwriter Otis Blackwell.
In 1958, the jazz singer Peggy Lee recorded it with almost nothing: a double bass, drums played very softly, and finger clicks. She also wrote new verses herself, about famous couples in history: Romeo and Juliet, and Captain Smith and Pocahontas. Her version became the most famous one.
In the song, every time the singer is with the one she loves, she gets a fever. When he holds her, she burns. It happens every time: it is a law of nature, like fire.
If you heat water, it boils.
Listen: the fever

Listen once. What happens when he holds her? Which famous couples does she sing about?

Then answer Section A. Count the finger clicks!
The zero conditional

When you kiss me, I get a fever. If you heat water, it boils.

If / When + present simple, present simple for things that are always true: facts, science, habits, rules. If you mix blue and yellow, you get green.
If or when?

When the sun goes down, it gets cold. (always) If it rains, the streets flood. (only sometimes)

In the zero conditional, if and when are often almost the same. when = it always happens; if = it happens only in that case.
Zero conditional with the imperative

If you have a fever, stay in bed. If it gets worse, call the doctor.

For advice and instructions: If + present simple, imperative. Very common in instructions and medical advice.
Sophia’s comparison: Sappho’s fire

Sappho wrote that when she sees the one she loves, a thin fire runs under her skin, her eyes can’t see and her ears ring. Love as a fever, six hundred years ago!

And in the Song of Songs, love’s flames are flames of fire, a very flame of the Lord.

So poets have always had a temperature.
