Vendetta' - a mafia themed cop thriller starring Italian actor Stelio Canelli (Barbarella, Django, Planet Of The Vampires). The theme for the show was composed by John Barry who also composed the Danny Scipio Theme that was used as a part of the score. John Baker produced all the incidental music.
I think Timmer should be interested; what about TallGuy?
Indeed - and all the other Barryistas on the board, most of whom will surely have the Vendetta and Danny Scipio Themes in their collection, and this might make an interesting bedfellow. I barely remember the series myself, but from the description of the music, I imagine it'd be a curiosity rather than something to listen to repeatedly, but samples (if any) might help on that one.
It could be similar to that fantastic jazz combo library music that Alan Tew wrote and which was used in The Hanged Man TV series in the 1970s and, latterly, in Black Dynamite.
