Dateline Diamonds (1965)

A highly enjoyable crime caper which weaves in various real pop stars and DJs into mid-1960s Swinging London. Fairclough (William Lucas) is a prolific diamond thief, however he needs a way to get his spoils out of the country. He blackmails Benson (Kenneth Cope), the manager of up and coming group the Small Faces (pre Rod Stewart), to take the diamonds aboard the radio boat in the channel where it can be passed onto Fairclough's continental contact...

Meanwhile the police Tom (Conrad Philips) and Paul (George Mikell) are finding it hard to get going with their investigation, but then they get a break when Fairclough is caught in the background of a press photo of the Faces and some information from Tom's Faces fan daughter Gay (Anna Carteret)...

As a crime drama it is a bit basic, though competent (the scene which shows in detail Fairclough doing one of his blags is fascinating) but add the pop star cameos which include Kiki Dee and Kenny Everett it is a perfect time capsule of Swinging London and some pretty good tunes.
