Who walks in when I walk out?
And who gives you that "Hi, baby"?
Who's it who got me jealous of you?

Who walks in when I walk out?
Now, don't you know you're my baby?
Who's it who got me worrying too?

Now when we kiss, I kinda miss
Something that used to be
Every day while I'm away
I get a feeling that you're fooling me

Oh, who walks in when I walk out?
And who gives you that "Hi, baby"?
Who's it who got me jealous of you?

When we kiss, I kinda miss
Something that used to be
Every day I'm away
I get that feeling you're fooling me

Who walks in when I walk out?
And who gives you that "Hi, baby"?
Who's it who got me jealous of you?
Got me jealous of you?

Louis Armstrong

Louis Armstrong, known throughout his lengthy career by nicknames like “Satchmo”, “Pops” and simply “Louie”, was a trumpeter, composer, singer and occasional actor, as well as one of the most influential figures in the history of jazz.

Born and raised in New Orleans, where jazz itself is alleged to have began, Armstrong started his career in 1918, playing the cornet in brass bands and riverboats along the Mississippi River. There, he caught the attention of his future mentor, King Oliver, joining his band in Chicago, where he networked with other popular jazz musicians like Hoagy Carmichael and his first wife Lil Hardin Armstrong.

In 1924, Louie relocated to New York City playing for the Fletcher Henderson Orchestra. It was at this time he switched over from cornet to trumpet in order to blend in better with the other musicians in his section. It was also when he developed his emotional playing style, which included singing and telling tales of his life back in New Orleans.
