Good find. Lyle Waggoner seemed to be destined for the DC Universe ... although he didn't get the part of Batman, he did later play another DC comics character, Wonder Woman's love interest, Steve Trevor, on three seasons of that show. He also appeared in that embarrassing "Return to the Batcave" movie that aired on CBS a few years ago.
I did like the large, no oval bat symbol on Waggoner's costume in that footage, as well as some of the dialogue referring to his parents' murder and his training as a crimefighter. The murder of the Waynes was only briefly mentioned one time in the Adam West series.
