Filmed in the months before MidAmeriCon, the 1976 Worldcon. Featuring Dean Gahlon, Denny Lien, Jim Young, and a kazoo orchestra best left unnamed.
Kudos to David Dyer-Bennet and to Joe Siclari and Edie Stern for getting this and other tapes from the Scott Imes Video Archive online!
Other videos recently added to the FANAC Fan History channel include Joe Haldeman singing Stan Long and other videos from MidAmeriCon, Noreascon 2 and 3, Aussiecon, the Hugo Ceremony from Suncon (Attn: kaffy_r!), and more. So far, the only two I was present at when filmed were Outworlds Live! at Corflu IV (1987) and Ted White interviewing Walt Willis at MagiCon (1992).
One event totally blew me away: Science Fiction's 50th Anniversary Family Reunion at Noreascon 3 in 1989. It was brilliantly conceived and staged by Ellen Franklin. And, hey, coffeeem you're in it! (Starting at 1:03:40.)
As is SFWA's newest Grandmaster, Jane Yolen, back when she was "one of the middle-aged dinosaurs" (30:34-33:00). Highly recommended.
