DALLAS – The Morning Musers are cutting things back a little bit, to borrow a phrase from one of their own. The longtime staple of DFW morning drive radio — the Musers trio of Craig Miller, George Dunham and Gordon Keith on Sportsradio 96.7FM/1310 AM “The Ticket” — will reduce their daily schedule to 6 a.m. to 9 a.m. The Musers for the past three decades have broadcast daily from 5:30 a.m. to 10 a.m. They announced their new schedule Monday morning, after returning from their usual holiday break.
