The theme tune, “I Could Be So Good for You”, written in 1979 by Gerard Kenny and Patricia Waterman, was sung by Dennis Waterman.
It was released as a single in October 1979, credited to ‘Dennis Waterman with the Dennis Waterman Band’, but failed to enter the charts. It was then re-released in October 1980, upon which it became more successful, peaking at No.3 in the UK Singles Chart in November.
