The Happy Organ. The sun is shining, it’s 53 degrees – time to rock it. I love playing this piece. I never play it the same way twice! You just get rolling and have fun – mistakes and all. The Roland organ does a great job for this piece. I hope it brings a smile to your face or at least gets your foot tapping. “The Happy Organ” is the name of an instrumental composition made famous by Dave “Baby” Cortez in 1959. Cortez co-composed it with noted celebrity photographer James J. Kriegsmann and frequent collaborator Kurt Wood. A significant portion of the tune bears a strong resemblance to the traditional “Shortnin’ Bread” tune.
