Here’s the story of how 10cc’s “I’m Not in Love” was produced. Long story short: they used the mixing board as a keyboard to blend in the 16-track recordings of the voices with the instrumental track (the kick drum part was actually played on a synthesizer), and the studio secretary saying, “Be quiet, big boys don’t cry.”

If you’ve got 10 minutes or so to spare, give it a look.

The song was used quite effectively during the sad opening scene of Marvel’s Guardians of the Galaxy.
