Actually I much prefer a rodeo announcer who doesn't feel the need to bring along a DJ to play music.  Surprisingly some of the very best announcers past and present just announce the rodeo.  Want to hear music get in your car and turn on the radio or go to a concert.  We are here at a rodeo to watch horses buck.  If there is too much dead space in the show that is up to the arena director to fill by keeping things moving.  Some of those old contractors would certainly cuss you if you weren't ready to go and it didn't matter who you were.  If you were never cussed out by the late Reg Kesler you have never experienced a real cussing.
