Sitcom Quiz Question - Junior Royal Road

[EverClean]

It's a quiz on sitcoms (UK or US, TV or radio) and I'm stuck on one clue-

Junior royal road (4,6,7)

Any help will be gratefully appreciated!

[EverClean]

I can't believe that it's stumped AB as well!!!!

[scorpiojo]

Yep :( ..something terrace? George something?

.... or passage. parkway, roadway, highway

[Calibax]

There's a radio comedy King Street Junior but that does not quite fit the letters and junior is in the cllue too

[hc4361]

I'm convinced that it is King Street Junior with an error either in the letter count or the quiz setter has put an s at the end of Junior.

A long running radio sitcom

[fiction-factory]

Yes, the setter may have misremembered the title- although I'm not sure why Junior would be in the clue and in the answer.
I did recall an Earl Street programme but that was Soap

[hc4361]

Although a junior royal would be a prince which does fit in the middle word.

[fiction-factory]

Or middle word could be George (or maybe Edward if he's classed as a junior royal)

[hc4361]

Or even Andrew

Thanks for all your input. I'm more and more convinced that the setter has got something wrong.
