He then joined the Raindrops vocal quartet (together with Len Beadle, Len's wife Jackie Lee and Vince Hill), which appeared on the television programme "Drumbeat" and subsequent LP. It was on this show that he met Oscar-winning composer John Barry, with whom he was soon to work, and the singer Adam Faith. Worth had aspirations to be a songwriter, and though initial attempts had failed, he asked pianist Les Reed to arrange a demo of his song "What Do You Want?". Faith, record producer John Burgess and Barry liked it, and with Barry's arrangements, Faith took the song to number one in the UK Singles Chart in November 1959, within which it remained for nineteen weeks. Worth's concern was that as he was still signed to Oriole, he should adopt a pseudonym, and combined Reed's first name with his own telephone exchange, to become Les Vandyke. He provided Faith with his follow-up number one "Poor Me", in January 1960, and for the next two years penned a further six Top Ten British chart hits for Faith: "Someone Else's Baby"; "How About That"; "Who Am I"; "The Time Has Come"; "As You Like It" and "Don't That Beat All". Worth also wrote another chart-topper "Well I Ask You" for Eden Kane, a pseudonym for Richard, the eldest of the three Sarstedt brothers, as well as Kane's two follow up hits, "Get Lost" (reached No. 10 – September 1961) and "Forget Me Not" (No. 3 – January 1962). At least two Vandyke songs were covered by well-known Australian artists: "Doin' The Mod" by Ronnie Burns's band the Flies (1965, first recorded by Vandyke with British band The Bambis, 1964) and "Dance Puppet Dance" by Little Pattie (also 1965, first recorded by Dave Duggan on Columbia in the UK, 1963), which reached number twelve in the Sydney-based pop charts. Vandyke also wrote music and songs for a number of low-budget movies during the 1960s and 1970s. These included "What a Whopper" (1961 as Johnny Worth); "The Kitchen" (1961); "Mix Me a Person" (1962, as Johnny Worth); "Some People" (1962 as Johnny Worth – lyricist); "Johnny Cool" (1963 as Les Vandyke); "Psychomania" (1973) and "The Playbirds" (1978 as John Worth); plus "Saturday Night and Sunday Morning" (1960).
