Devlin:
I was just reading about Dana Elcar's blindness up on IMDB.COM. It seems he went blind at a fairly young age (early 60's I think). He was born in 1927. I've just been reviewing some of his scenes with Roger, Sam and Burke. I had forgotten how funny and sharp some of the dialogue was between them.
All I can say is 'Thank You, Thank You' to DCP for having the mind to save these early episodes. They are wonderful to see again after all these years. A real treat if you will in today's TV land of unviewable programming.
