Lou was the female member of the Lubbock Lou and his Jughuggers jug-band. She served as the group's vocalist and also played tambourine.
Lou debuted in The Muppet Show episode 208, and would appear periodically throughout the run of the series, often paired with Slim Wilson. She was featured on the albums The Muppet Show 2 (singing "Borneo"), and The Muppet Show Music Album (as a lead on "Henrietta's Wedding.") In the latter, her name was identified on the album's sleeve. She also made cameos in the first three Muppet films, most notably as a Happiness Hotel resident in The Great Muppet Caper.
