Trollcops (Radio Play) (by Erik “Jit” Scheele, with words by Nick “OMGTSN” Smalley) is a bonus track that takes that base Trollcops melody to its logical conclusion. Well, not quite: this version seems to have come first (according to the liner notes), with the instrumental version following. Regardless, the voiceover’s great, with that stern, staccato ‘30’s cadence.
For a little bit of atmospheric context, check out the introduction to Dragnet from the early '50’s.
