SHE is probably the most travelled singer in the world. Her name is known from Israel to Canada and from Spain to Australia. She had just completed a sensational month-long tour in America, and by the end of this year it is reckoned that she will have sung in twenty different countries. Tonight Petula Clark the delightful English-born singing star, begins a series of six BBC-tv shows. The first four will be transmitted 'live.'
     Pet now lives in Paris with her French husband and two children. The timetable during the week before she arrived in London for the series is typical of the tempo at which she lives. She flew from America to Paris after her tour. Following a night's stop-over in Paris she went to Italy for a TV appearance, then back briefly to Paris, and then on to London.
     Pet has been looking forward to doing this series for a long time. She will be here for six weeks and hopes to see a lot of London.
     During the show Pet will be introducing British audiences to some artists from the Continent.

     Although she's British and a chart-topper with her waxings, Petula Clark has been under-exposed on local tv, apart from guest spots in disk shows. While she's in London for a cabaret stint, BBC-I has nabbed her for a skein of six, and the opener shaped as a lively entry, not especially imaginative in its presentation, but adequate for the songalog in view
      Miss Clark has an easy informality that might have registered more if she'd had something rather more witty to say. Apart from a gag about the Common Market, she contended herself with a reprise of her repertoire, plus a fortaste of her latest waxing due for release next week. This "I Couldn't Live Without You,"[editor's note: Presumably "I Couldn't Live Without Your Love] had Top-10 written all over it, and made a lively wind-up to the routine.
      A feature of the series will be guest warblers from Europe, and the first, Claude Francois was a so-so arival, with an anguished voice but a brisk line in energetic terping. Band backing was first rate, and a decided plus were Tony Hatch's orchestrations, which suited Miss Clark's jaunty style perfectly with build-in fan audience, the show should click, but Yvonne Littlewood's production would benefit from a few more visual surprises to relieve the notes.
