One of the best and most original rockers of the early '60s, Del Shannon was also one of the least typical. Although classified at times as a teen idol, he favoured brooding themes of abandonment, loss, and rejection. In some respects he looked forward to the British Invasion with his frequent use of minor chords and his ability to write most of his own material. In fact, Shannon was able to keep going strong for a year or two into the British Invasion, and never stopped trying to play original music, though his commercial prospects pretty much died after the mid-'60s.
