Little Jerry's original hippie apparel was exchanged in the 1980s for a white and black leather jacket and a chain necklace. In the band's comeback appearance in a 2000 episode, he also sports a pair of sunglasses.
Little Jerry is considered to be male, but in one Shalom Sesame sketch, in which an actress dubbed the character for "Proud," host Mandy Patinkin introduced the rocker as female: "Little Jeri (sic) is loud and proud, and why shouldn't she be?."
Little Jerry was named after his performer Jerry Nelson, who later talked about the character and his group in a 2009 interview:
“Little Jerry was Jeff Moss’ thing. I think deep in his heart he wrote that because he loves to sing bass. They were wonderful pieces. They were so much fun to do.”
- Although Little Jerry usually appeared as a redhead, he had black hair in one sketch where Grover talked about the word "exit." (EKA: Episode 0261)
- A similar looking Green Anything Muppet bandleader (and drummer) sang "Spinning Wheel" during Sesame Street's first season. A background hippie closely resembling Little Jerry appeared in two first season sketches, the "Before and After song (First: Episode 0047) and the "Forward" and "Backward" skit.
