In 2004, Canadian Michael Buble was beginning to make a name for himself by revisiting a bygone era - a time before the Beatles, when simple tunes were hits and crooners such as Paul Anka and Bobby Darin were crowned the kings of music. Oldies like "Put Your Head on My Shoulder" and "Come Fly With Me" certainly aren't the tracks you'd expect to hear on a 28-year-old's first major CD. This is exactly why Buble's apparent overnight success may have come as a surprise to those used to the style-over-substance that dominates the charts.
