Don’t blame CBS, it is actually the local affiliates’ decision to run their “if it bleeds it leads” late local news instead of letting the concert finish.
Yeah, you can blame CBS:
When the Post reached out to CBS for comment, the network responded with the statement, “A network programming timing error ended last night’s Billy Joel special approximately two minutes early in the Eastern and Central Time Zones. We apologize to Mr. Joel, his fans, our affiliated stations, and our audience whose viewing experience was interrupted during the last song. Due to the overwhelming demand from his legion of fans, BILLY JOEL: THE 100TH – LIVE AT MADISON SQUARE GARDEN will be rebroadcast in its entirety on CBS on April 19th at 9:00PM ET/PT.”
