What is the song of spring rain pouring down the street like oil?

The lyrics "Spring Rain is as expensive as oil and flows all over the street" come from the song "Spring Rain". The lyrics are as follows:

spring rain

I walked with him under an umbrella in the drizzle.

Heart to heart, hand in hand.

A smile, a drunken spring rain, is as expensive as oil.

It is more expensive to rain all over the street.

Spring rain is as expensive as oil.

It is more expensive to rain all over the street.

Live together, until the white hair is raining.

Walking under the umbrella, I shook hands with him.

A smile, a drunken spring rain, is as expensive as oil.

It is more expensive to rain all over the street.

Spring rain is as expensive as oil.

It is more expensive to rain all over the street.

Spring rain is as expensive as oil.

It is more expensive to rain all over the street.

Spring rain is as expensive as oil.

It is more expensive to rain all over the street.

Live together until the end of my life
