There's an old British TV series. I'm not sure what its exact name was. It was translated into my native language as 'newspaper boys' or 'paper delivery gang'. It was about some gang of children delivering newspapers on bikes and doing other 'detective' stuff in the meantime. The theme song was by this singer with a voice like bells. Does anybody know the series or the theme song?
when you say 'old TV series', exactly how old are we talking about? I can't help you with the singer but the programme could possibly have been Press Gang in the late 80s with Julia Sawalha and Dexter Fletcher.
