Rearranged by conductor Mike Perjanik, this is a cover version with its own style, favouring strings and oboe over the brass and drums of the original. The result, as Richie Unterberger puts it, is quality British-style orchestrated girl group-soul-pop.
Dinah Lee, known as 'The Dynamic' Dinah Lee, was born Diane Jacobs in 1943. Her rocking versions of astutely chosen songs and her cutting-edge mod image made her extremely popular in New Zealand and Australia in the mid-60s.See, for example, Do The Blue Beat and Don't You Know Yockomo.
#1 in NZ? This has been called a #1 NZ hit, but as there were no functional NZ charts at this time it is hard to verify.

San Francisco singer Lydia Pense became better known for fronting jazz-rock band Cold Blood, formed in the late 60s and signed by Bill Graham for his Fillmore West venue. A re-formed line-up of Cold Blood was still touring as recently as 2017, with Pense as lead singer. Her voice has been described as strong, powerful, raw, beautiful or stomping.
This seems to be an overlooked composition by Joseph Brooks (1938-2011) who wrote You Light Up My Life (1977), the song that kept Debbie Boone at #1 on Billboard for 10 weeks and became the top-selling US single of the 1970s. It was the title song of the film which was written, produced and directed by Brooks.
