Tannhauser was a German knight/singer/poet from the 13th century who apparently gave into his sinful lusts one night (i don't know the details) and later sought absolution for his sins. To derive is to trace to a source. Perhaps Dennis has a similar story, and wants to know exactly what made Tannhauser give in, so he can find out why HE did whatever he did. Even the scarce lyrics here support this theory.
"Boredom won't get me tonight"
"Let's bring this city to life - to light - tonight"
