Networks don’t have license to transmit band music.
I did not know that. Are you sure? It seems like that would not be a problem but I sure don’t know.
Why don’t the networks show the cheerleaders anymore?
Gee, then how did they broadcast all the bands in the New Year's Day parade? Stupidity on display on your part. And, just so you know, the networks don't have licenses, it's the individual tv stations that are licensed.
