Creator Breakdown: "Precious" is about Martin's divorce; "Clean" is inspired by one of Dave's many rehab visits, and "Barrel of a Gun" is inspired by Dave's attempted suicide. And nearly everything on Songs of Faith and Devotion was the result of tensions between the band members nearing breaking point.
Conversely, "Home" is often interpreted as Martin writing/singing from Dave's perspective after getting sober.
Old Shame: Several - the albums "Speak and Spell" and "A Broken Frame", "People Are People" (Martin is now embarrassed by the simplicity of the lyrics despite the fact that it was a major worldwide hit), Martin's cross-dressing phase (he still has to field embarrassing question about this nearly 30 years later), the choreography in the "Master and Servant" video.
The Pete Best: Vince Clarke, their initial keyboardist/songwriter. When he departed after one album, many thought the band was doomed, which is not exactly how it played out.
