This is Frank Zappa's appearance on "Thicke of the Night". My records indicate a broadcast date of March 17, 1984. Internet searches reveal March 30, 1984 as the original broadcast date. Either way, here it is.
Well, Frank probably got lucky with the prostate cancer after all. If this is what he thought of music in the 80's, the poor guy would probably kill himself anyway after hearing the shit we call "music" today.
