Tarcher worked closely with her mother as producer of "Lamb Chop's Play-Along" and "The Charlie Horse Music Pizza." Jeremy Tarcher had also been part of Shari Lewis's shows on PBS. After her mother's death in 1998, on the advice of family and family friend the late Dom DeLuise, Tarcher decided that Lamb Chop should live on for her many fans. In 2009, she started performing with Lamb Chop. It was during this time that she changed her surname to her mother's, Lewis, as an homage. While Lamb Chop may be described as "sassy", "please" and "thank you" are part of the repertoire. Lewis has the same hand size as her mother.
