I've been in touch with my friends who open What's My Line Live on Stage tonight in New York at the Barrow Street Theatre. My sister's been giving them a hand with off-stage matters (she's an actress and director herself) and is escorting one of the guest/contestants to the show this evening. Betsy Palmer, a regular on I've Got A Secret in the 1950s and 1960s, is one of the panelists.
Our friend Mark Evanier had a clip which shows many of the "Mystery Guests" from the Los Angeles run, which I will try to link here. You'll see a shot of the panel as Greg Proopst guesses Wink Martindale. At the far right, with his face obscured by a mask that can't obscure his lovely head of hair, is my husband Len Wein.
If you are in New York on a Monday night over the next six weeks, go see the show. It's a fun evening and Len will be a panelist on April 21.
