If there is an afterlife, the lyrics will promise that song.

This sentence should come from San Mao's poem. In addition, there is no such sentence in Sitar tan's song "If there is an afterlife".

Poetry:

If there is an afterlife, be a tree,

Standing forever. Without sad and happy gestures,

Half in the dust,

Half of them are flying in the wind;

Half in the shade,

Half bathed in sunshine.

Very silent and proud.

Never rely on, never look for.

If there is an afterlife, it will become a gust of wind.

Instances can become eternity.

No sentimental feeling,

No sentimental eyes.

Half of them are free and easy in the rain,

Half of them travel in spring;

Lonely, lonely travel,

Take away those vague ideas,

Never missed, never loved;

If there is an afterlife, be a bird,

Through eternity, there is no trouble of getting lost.

There is fiery hope in the east and warm nest beds in the south.

Drive the sunset back to the west and awaken the fragrance to the north.

If there is an afterlife,

I hope that every time we meet,

Can become eternal.

I hope it helps you.
