I can’t believe we let this pass without documenting the lyrics.
Allegedly this was first recorded by Eva Taylor and Her Boyfriends in 1934, but I have not found an online recording.


THE STUFF IS HERE AND IT’S MELLOW
Words by Walter Bishop, & Clarence Williams; music by Willie “The Lion” Smith.
As recorded by Cleo Brown (vocal and piano), accompanied by guitar, bass, and Gene Krupa on drums; Decca 410 B, 1935.

Lock the windows and close the door,
Start the party up once more!
Hey, hey, let's get gay, 'cause the stuff is here.

Everybody grab a glass,
'Cause the good stuff's ‘bout to pass,
Hey, hey, let's get gay, 'cause the stuff is here.

Piano man falls upon his stool,
Plays that piano like he's nobody's fool.

Everybody grab that glass,
'Cause the good stuff's ‘bout to pass,
Hey, hey, let's get gay, 'cause the stuff is here.
