KILT/Houston Changes: CBS Radio KILT-FM (The Bull)/Houston morning host Greg Thunder will now handle the show solo as Corey Foley and Intern Bobbie exit and Cowboy Dave Bayless moves to nights. Bayless replaces Zakk United in that daypart, who shifts to afternoons following Keola Lui-Kwan's move to Top 40 sister KKHH last month (CAT 3/24). Foley and Thunder joined in late 2010 to replace the long-running Hudson & Harrigan show (CAT 11/12/10).
