Louis Armstrong was an American trumpeter, composer, singer and occasional actor. Renowned for his charismatic stage presence and voice almost as much as for his trumpet playing.

Louis Armstrong‘s influence extends well beyond jazz, and by the end of his career, he was widely regarded as a profound influence on popular music in general.

Louis Armstrong was one of the first truly popular African-American entertainers to ‘cross over’, whose skin color was secondary to his music in an America that was extremely racially divided.

Louis Armstrong was born into a poor family in New Orleans, Louisiana, and was the grandson of slaves and spent his youth in poverty, in a rough neighborhood known as the Battlefield, which was part of the Storyville legal prostitution district.

After dropping out of school at age eleven, Louis Armstrong joined a quartet of boys who sang in the streets for money.

‘When You’re Smiling’ is a popular song which was made famous by Louis Armstrong.

When you’re smilin’ keep on smilin’

The whole World smiles with you
And when you’re laughin’, oh, when youre laughin’
The sun comes shinin’ Through

But when you’re cryin’ you bring on the rain
So stop your sighin ‘be happy again
Keep on smilin cause when you’re smilin’
The whole World smiles with you

Oh, when you’re smilin’ keep on smilin’
The whole World smiles with you
Ah when you’re laughin’ keep on laughin’
The sun comes shinin’ through

Now when you’re cryin’ you bring on the rain
So stop that sighin’ be happy again
Keep on smilin cause when you’re smilin’
And the wholeWorld smiles with you

The great big World will smile with

The whole wide World will smile with you
