That same year Hare came to national attention in the role of Mrs Butler in On the Buses, taking over the part from Cicely Courtneidge in the second series of the ITV comedy. The series ran until 1973 and spawned three spin-off films On the Buses (1971), Mutiny on the Buses (1972) and Holiday on the Buses (1973) in which Hare recreated her small-screen role. The cast also performed a stage version of the popular series in Vancouver, British Columbia, Canada, in 1988.
