"Kid Cassidy" is coming to Salt Lake City.

One of the most popular DJs in Las Vegas, he will make his debut on KKAT (FM-101.9) radio on Monday, May 1, 5-9 a.m.Cassidy replaces "Gary and Scotty," who, according to John Marks, operations manager for KKAT, KODJ and KALL, were not fired but will be retained in other company positions - if at all possible.

Officials at other stations are surprised with the morning change of KKAT, especially because the new Arbitron ratings are due out next week. They don't understand why KKAT didn't wait another week to see the full ratings from last winter before deciding on the crucial morning time slot.

However, Marks said this change has nothing to do with the latest ratings.

He said KKAT tried to land Cassidy (real name John Potter) from KWNR, a Las Vegas/Hen-derson modern country station, about 18 months ago before Gary Zane and Scotty Christopher were hired.

"We had an opportunity," Marks said of hiring Cassidy now. "We chose to exercise the opportunity. We knew he was a quality guy. We took the opportunity to grab him."

Marks said station contracts for Gary and Scotty are still in place and so financially these two DJs will be fine for a while. KKAT has promised to do its best to find them other on-air jobs, even if they are at sister stations KALL or KODJ.

Marks said nothing is open for the DJs yet, but they are welcome to stay around, if that's their desire.

"They did not have a poor performance," Marks said of Gary and Scotty.

In fact, the DJs were the second-place morning team last fall among listeners ages 25-54 and fourth among ages 12-plus, according to Arbitron estimates.

So, why is Cassidy taking over mornings?

Marks said Cassidy is a huge morning talent, with 15 years' experience and KKAT is banking on a multi- year contract with him to take the station back to No. 1 spot in the Salt Lake market, as it was in the early 1990s under the former "Morning Guys" (Cano and Simmons).

"He wanted to be at KKAT," Marks said of Cassidy, who is 40-ish and who has been considered the No. 1 morning radio talent in Vegas for the past five years.

Marks said Cassidy's greatest ability is to cultivate a solid listener relationship.

"He allows the listener to be the star of the show," he said. "There's strong audience participation."

Debbie Dujanovic, morning news anchor, will remain in place. (She's the best new, no-nonsense news, traffic and weather reporter to come along in quite awhile on radio.) She will also apparently continue reporting for KTVX Ch. 4 news too.

"Insane" Rick Shane, long-time KKAT morning show producer, will also stay in his current role.

Marks said KKAT's current lineup of T.J. Evans (9 a.m.-1 p.m.); "Gentleman Jim" Mickelson (1-3 p.m.); Bob Wells (3-7 p.m.); Tracy Chapman (7 p.m.-midnight) and the syndicated Blair Garner show (midnight-5 a.m.) will remain intact.

Mickelson, who has been filling in on the morning show this week, will also continue as KKAT program director.

Regarding KKAT's new "young country" slogan, Marks said it's meant to convey the attitude of the station.

"It's a feeling and mindset we want to create," he said, explaining the station will continue to play a variety of artists but also has a large amount of the younger country artists.

He confirmed that KKAT is now more music-intensive than it has been in some time. The station has also spread out the commercials more evenly so that music is only stopped twice each hour.

Rival modern country music station KSOP has slipped ahead of KKAT in the ratings, so KKAT is surely hoping its "Young Country" angle and "Kid Cassidy" will reverse that trend.

- NEW TALK SHOW - David Bresnahan, a West Jordan Republican serving in the Utah House of Representatives, is the area's newest talk radio host. He has a new program - "Talk Back with Davis Bresnahan" - airing each Tuesday through Friday from noon-1 p.m. and also Sundays from 6-8 p.m. on KTKK (alias "K-Talk," AM-630).

According to Bresnahan, the show is to feature guests, a lively debate of current issues and listener call-in. Bresnahan did a trial show on a Sunday in April, and its success prompted a permanent program.

"You can expect to hear good, solid information on issues, interviews that will bring details on hot topics, as well as some lighter moments to keep it all fun," Bresnahan said.

John Price, long-time KTKK host, will continue his once-a-week show on Mondays from noon-1 p.m.
