KISS played Dick Clark's "ABC In Concert" for the first time and performed "Nothin' To Lose", "Firehouse", and "Black Diamond".  Interesting to note are the absence of "Deuce" and "Strutter".  These tunes are better, which was obviously acknowledged then, but more on that later.  Peter Criss was smoking on the vocals for "Nothin' To Lose".  "Firehouse" was very strong and true to the typical live-is-better-than-the-studio original KISS.  "Black Diamond" was as hypnotizing as it was very solidly, tightly played.
