Hey, thanks for the link. It's always fun when someone captures something off of a live "stream" to use that modern term, that might turn out to be the only actual capture. TV was more live than anything else back then. Ampex had not quite put video tape on the market. You could show actual movie film on TV or record film off of a TV monitor of a live broadcast, but this was not always done.
You are right about the quality. While certainly not Hi Fi in any sense, considering what could (and often did) go wrong between a live broadcast audio mix, TV reception in 1955, probably recorded with the microphone that came with the wire recorder off of the TV speaker, to a medium with no capstan speed regulation and a propensity for kinking, snarling and breaking. Then played back on an almost 60 year old machine and once again picked up acoustically off of the old machine's speaker for the video, then digitally compressed as a file to post it... Considering all that, it is about as good of a live Elvis as you might hear. There are certainly many many much worse sounding clips made by "professionals" in that era.
As the owner of much fine old junk (including a couple of wire recorders, one with a very similar mechanism) I can say it is rare to have a piece of consumer audio equipment of that era, operating that well without considerable restoration effort !
