The musical Pippin was originally conceived by Stephen Schwartz as a student musical performed by the Scotch'n'Soda student theatre troupe.[62] Schwartz also collaborated with drama student John-Michael Tebelak to expand his master's thesis project titled Godspell, created under the direction of Lawrence Carra, into a musical. While enrolled at Carnegie Mellon, acting students Michael McKean and David Lander (class of 1969) created the characters "Lenny & Squiggy". The pair continued performing the characters in live comedy routines before joining the cast of the TV series Laverne and Shirley.
