Good morning on this wishy-washy Wednesday.

Fifty years ago, the world heard Louis Armstrong’s flawlessly raspy voice sing “What a Wonderful World.”

He recorded the song in the summer, released it that fall, and in October of 1967, the melody made it to the Billboard easy-listening charts for the first time.

The song was inspired by a quaint, tree-lined slice of 107th Street in Corona, Queens, where Mr. Armstrong lived in a modest, red brick home for the last three decades of his life.

If you visit the location, now the Louis Armstrong House Museum, you’ll hear a recording of the musician describing the neighborhood:

“I saw three generations come up on that block. They’re all with the children and grandchildren, and they all come back to see Uncle Satchmo and Aunt Lucille. That’s why I can say I hear babies crying, I watch them grow, they’ll learn much more than I’ll ever know. I got pictures of them when they was 5, 6 and 7 years old, and it is a wonderful world.”
