The jazz (mostly) radio station I sometimes have playing while I sleep starts every weeknight overnight shift solemnly with trumpeter/bandleader Donald Byrd's 1964 recording of "Cristo Redentor."

A friend with whom I've sadly lost touch was so moved by the sign-off of a TV station in his town--back when television stations went off air for a while before resuming broadcasting in early morning--that he recorded it.

There are still numerous U.S. AM radio stations which only broadcast from sunrise to sunset; the country station in my town was so licensed, as was a station about 35 miles from me that nurtured my appreciation for pop and rock when I was a tween. If memory serves, I recall the latter station ended its broadcast day with Porky Pig's send off to many Loony Toons animated shorts. Would you appreciate it were a TV or radio station you like to end its day with Porky?
