We return this week with part three of our seventies vinyl bootleg series.     We revisit an era where it was possible to sell dscs containing the entire soundtrack of "Help!", "A Hard Day's Night" or "Magical Mystery Tour".     Surprisingly, even in the era of near-perfect digital reporoduction, there remains historical value in these artifacts.     Beyond these archival treasures (and their contemporary online equivalents), the "not the Beatles" story finishes up for now, with Peace of Mind (Candle Burns), a ditty whose origin remain a mystery to this day, and a track which is perhaps more popular as a fake Wings song on a Beatles bootleg than its actual, quite legitimate release.
