Kolchak-wise, there were four composers on the Universal series: Gil MELLÉ, Jerry FIELDING, Luchi DE JESUS (a universal TV composer of that era), Greig MCRITCHIE (the arranger of Jerry FIELDING).
So it's a bootleg......I thought I had missed out on the real deal.
I'm watching the KOLCHAK: THE NIGHT STALKER bluray set for the second time---one episode followed by its commentary every Friday night like when I first watched the series back in 1974. On the commentaries, most of the writers and historians rave about the theme song.
