On 9 March 1966, Springfield had an instrumental track of Donaggio's composition recorded at Philips Studio Marble Arch. The session personnel included guitarist Big Jim Sullivan and drummer Bobby Graham. Springfield still lacked an English lyric to record, but Springfield's friend Vicki Wickham, the producer of "Ready Steady Go!", wrote the required English lyric with her own friend Simon Napier-Bell, manager of the Yardbirds. Neither Wickham nor Napier-Bell had any discernible experience as songwriters. According to Napier-Bell, he and Wickham were dining out when she mentioned to him that Springfield hoped to get an English lyric for Donaggio's song, and the two light-heartedly took up the challenge of writing the lyric themselves: "We went back to 's flat and started working on it. We wanted to go to a trendy disco so we had about an hour to write it. We wrote the chorus and then we wrote the verse in a taxi to wherever we were going."
