I Only Want to Be with You

Mike Hawker and Ivor Raymonde wrote it, and Johnny Franz produced it for her debut as a soloist. She recorded it on 25 October 1963 at Olympic Studios, with Raymonde arranging and conducting, Keith Grant engineering and the Breakaways in the vocal chorale. The arrangement follows the Wall of Sound approach, with backing singers, double-tracked vocals and a horn section, an approach inspired by groups such as the Shirelles. It was released in November 1963, three weeks after the Springfields' last concert.

It reached number four in Britain in January 1964 and number twelve in the United States. She sang it on the first ever Top of the Pops, on 1 January 1964. A 1988 re-release, timed with a soft-drink commercial that used it, peaked at 83 in Britain, and it served as the theme for the HBO sitcom Arliss from 1997 to 2002. She also recorded a German version, Auf dich nur wart' ich immerzu. The Guardian's obituary heard in it a move toward the girl-group sound of the Ronettes, the Crystals and the Chiffons.
