More What's My Line?

This Mystery Guest segment of What's My Line? surprisingly and wonderfully fits in perfectly with a couple of recent postings that began with Robert Preston and subsequently dealt with shows such as Peter Pan and mention of Cyril Ritchard.  Here is Captain Hook himself as the Mystery Guest -- and as luck would have it, one of the panelists is...Robert Preston!  The broadcast is from December 22, 1957, and Preston was then-appearing on Broadway in The Music Man.  The TV quiz show was done on Sunday nights and broadcast live, which is when Preston's musical had no performances and therefore how he was able to be on the panel, and relates to his quip when introduced.
