Cole Porter wrote “Night and Day” for the 1932 musical play Gay Divorce.
Here is a young Frank Sinatra way back in 1956.

Fred Astaire introduced “Night and Day” on stage, and his recording of the song was a #1 hit. He performed it again in the 1934 film version of the show, renamed The Gay Divorcee, and it became one of his signature pieces.

The song was so associated with Porter that when Hollywood first filmed his life story in 1946, the movie was entitled Night and Day. wiki

Here’s Haydn Huckle on the piano.

Night and Day Lyrics

Like the beat, beat of the TOM-TOM
When the jungle shadows fall
Like the tick tick tock of the STATELY clock
As it STANDS against the wall
Like the drip drip drip of the rain drops
When the summer shower’s through
So a voice within me
Keeps repeating you…you

Night and day
You are the one
Only you beneath the moon
And under the sun
Whether near to me or far
It’s no matter, baby, where you are
I think of you
Night and day

Day and night
Why is it so
That this longing for you follows wherever I go
In the roaring traffics boom
In the silence of my lonely room
I think of you
Night and day

Night and day
Under the hide of me
Though such a hungry yearning
Burning inside of me
This torment won’t be through
’til you let me spend my life making love to you
Day and night
Night and day

Night and day
Under the hide of me
Oh, such a hungry yearning
Burning, burning inside of me
This torment won’t be through
’til you let me spend my life making love to you
Day and night
Night and day
