I loved that series, and the theme music was some of the most inspiring I’ve ever heard, written and conducted by Stanislaw Kaper, you only had to hear it once, and you never forgot it.
It has been rumored for decades that J. Edgar Hoover personally approved the selection of Zimbalist for the starring role in the ‘F.B.I.’.
One of the good guys, Zimbalist is a devout Christian and a true American patriot.
