Career Copywriter Rushdie worked as a copywriter for the advertising agency Ogilvy & Mather, where he came up with "irresistibubble" for Aero and "Naughty but Nice" for cream cakes, and for the agency Ayer Barker (until 1982), for whom he wrote the line "That'll do nicely" for American Express. Collaborating with musician Ronnie Bond, Rushdie wrote the words for an advertising record on behalf of the now defunct Burnley Building Society that was recorded at Good Earth Studios, London. The song was called "The Best Dreams" and was sung by George Chandler. It was while he was at Ogilvy that he wrote Midnight's Children, before becoming a full-time writer.
