Harry Connick Jr. is an American pianist, singer, composer and actor from New Orleans. He has released many albums and perform frequently with his own big band. “Do Dat Thing” is a real “feel-good” song composed in New Orleans style. The tempo must not be too fast. A kind of rough, heavy groove is preferred. When staccato is notated, the 8th notes have to be straight. The notations in the Drums-part is optional. From 35, the rhythm in the bass-line is meant as information for the musician. Be aware of the dynamics from the beginning (not too loud) to give it a “lift” at the end of the piece.
