Al's a familiar face to those who follow the old TV scene. He looked like one of my friend's dads, or a teacher, or the liquor store guy. Someone who just wandered on to the set.
Al's ability to portray a helpful, anonymous bystander for a moment or two, then disappear in the ultimate flow of the story, gave him lots of work on TV and in the movies. He was a totally indistinguishable everyman-- a quality which, paradoxically, made him stand out. I'd always say, "Hey, it's Al Checco!"
Not that he had anything to do with audio, but I thought he was a pretty cool character actor from that era.
