Saw this video (below) on YouTube this week, recorded on 12/18/1957. At first it looked like it was received at WFIL-TV (Channel 6 in Philadelphia). But I noticed it looked like the Postal Service PSA was already in progress by the time the switch was made to WFIL-TV after the ABC promo and Network ID had finished. I also noticed a quick frame or two of an American Bandstand slate before the switch to WFIL-TV was made. I also noticed the audio from WFIL had that "network sound" like it used to be prior to January of 1978 when full-quality (15 kHz) lines were introduced. Could have this been recorded either at ABC New York or some ABC affiliate "down-the-line"? Was ABC using the WFIL-TV legal ID as a kind of "cue" for the affiliates to use before they were to return to the network after the local break or was WFIL-TV recording this, post-network feed? It's a very interesting look on how American Bandstand was sent to the ABC network in those early days of TV. Any thoughts??
