"Thunder and Lightning" b/w "The Coming of Kohoutek"

According to Russo's Collector's Guide, fifty years ago to-day (2 September 1974), Argent's "Thunder and Lightning" (edited) b/w "The Coming of Kohoutek" (Epic 8-50025) was released in the U.S. and Canada.  This seems to be the last single Argent released in these countries; Russo doesn't list any more.
