Really a brilliant idea.

The radio station was portrayed as promoting a big concert through most of that episode, barely mentioning The Who by name that I recall, and it seemed like a "normal" installment for the first part of the television programme. The latter minutes somberly dealt with the tragedy and tried to bring attention to problems with "festival" (general admission) seating for such venues.

A search says WKRP "In Concert" episode is viewable at https://m.youtube.com/watch?v=qSeWECDb3YM
Edit: s/never/barely/;s/20 minutes or so/part/
Still, very cool, and a little jealous of the on-air staff that get to work there.
