Rossini, the Lone Ranger, and dating oneself

I was listening to Public Radio when a familiar theme came on - "out of yesteryear", "thundering hooves", and "from WXYZ, Detroit".  It was the "William Tell Overture" performed last week as part of the Minnesota Symphony's Sommerfest.  I didn't hear any shouts of "Hi Ho, Silver" at the end, but the announcer, Allison Young, remarked some in the audience had shouted that.  She also mentioned the familiar TV show.  Wait a minute, young lady, it was a radio show!
