I feel fortunate to own a (extremely poor quality) copy of this eppy-sode ... it was tacked onto the end of a VHS tape of the (semi-poor quality) complete 2-part British Arena show version of the Debbie Geller documentary "The Brian Epstein Story" that I lucked into finding! ♥ Brian ... only wish I could see his face clearly on this tape.
