In both series, the part of Arthur Lane was played by Fine Time Fontayne.
The main characters, Johnny Street and Arthur Lane play partners in a small Yorkshire building firm.
The series records their rather odd experiences in Yorkshire suburbia, doing a variety of small and large jobs for householders.
Lane worked for Street's father in the firm, which apparently suffered from certain financial irregularities.
The "lady with the boiler on Misperton Avenue" is a fictional customer used as an all-purpose excuse for not being able to take on a job right away (the builders do not want to seem desperate for business) or for making a quick exit from an embarrassing situation.
