First recorded (as “Crooked Little House”) by Jimmie Rodgers (1960).
Hit version by The Serendipity Singers (US #6/MOR #2 1962).
From the wiki: “‘Don’t Let the Rain Come Down (Crooked Little Man)’ was written by rockabilly singer-songwriter Ersel Hickey, with the lyrics based on the English nursery rhyme ‘There Was A Crooked Man’, arrangement with a Calypso-based melody. It was first recorded in 1960 by country singer Jimmie Rodgers (‘Honeycomb’, ‘Kisses Sweeter Than Wine’) with no apparent chart impact. (This Rodgers is not to be confused with Country music pioneer Jimmie Rodgers).
“In 1962, ‘Crooked Little Man’ was covered by The Serendipity Singers as their debut recording, and it charted Top-10 on both the US Billboard Hot 100 and Easy Listening charts that year.”
