Pru and Tim did an excellent job and I always assumed the show would discontinue when they retired, however Sheila and Gyles were excellent in this, their first episode. Whilst the new pair are complete novices to canals and are friends rather than spouses, the attitude is the same - live life to the full in spite of age etc. With their quick dialogue, this is the funniest episode so far (although their next episode is too smutty).
