How to kickoff ERRguitar? Go with a neglected classic of course. Ennio Morricone's film score to the 1968 Mario Bava cult classic Danger: Diabolik clearly fits the bill. If you're not familar with this Italian/French pop gem starring John Phillip Law as the criminal mastermind/hero from the popular Italian fumetti (comic book) series, get busy. After years of enduring inferior VHS copies it can a great relief to finally enjoy in a proper presentation in DVD.Here's the haunting psychedelic theme song Deep Down sung in Italian (the opening title renders it in English).

Deep Down - Ennio Morricone (Parade 5052)
And the theme two more times as Emerald Bikini and The Pyrite Wink.
And finally a swinging number (very Morricone too) Under Wah-Wah (the "wah-wah" referring to a scheme to extract Au from H2O).
