“When you hear the swirling synths and clattering beat that open ‘If You Leave’ by Orchestral Manoeuvres in the Dark (OMD, for short), you just might be transported to some long-ago theater, or maybe back to nights at home with the VCR running,” (American Songwriter). “Or maybe, just maybe, you’ll recall the nervous excitement of a high school dance. This ‘80s anthem has a way of evoking nostalgia for that era like few other songs. In fact, the song is such a perfect example of desperate romanticism that you might imagine it to be one that was toiled over for weeks in an effort to make it the perfect fit for what would turn out to be an iconic movie scene. But what if we told you it actually was written and recorded in the span of an evening or so?
… Luckily, one of (OMD’s) U.S. fans was John Hughes, the noted writer and director … He contacted OMD to submit a track for his 1986 film Pretty in Pink … In around 14 hours, Andy McCluskey and Paul Humphreys wrote ‘If You Leave’ and created a rough mix. Once Hughes heard it the next morning, he was blown away, which meant that OMD had to get back to the studio on just a few hours sleep to polish up the track for an official recording … Even though it was rushed and put together without any kind of forethought, ‘If You Leave’ delivered just what OMD wanted. The song went to the Top 5 in the U.S., and it hasn’t ever quite departed from the public consciousness since … they ended up with a stone-cold classic …”
The tune is built around such a simple melodic idea (re-mi-do) carried from the verses into the chorus, paired largely with a cliché chord progression (I-vi-IV-V or I-IV-V-IV), that it’s difficult to imagine how this tune could work without a key change. No need to worry — there are ten! Starting with a shift from F major to D major before the vocal even makes an appearance (0:17), various sections of the tune shift among the keys of F, D, G, and E major.
