There's a new, old familiar voice on TK-99's evening shift. Mimi Griswold, host of the station's popular Sunday morning show The Blue Moon Cafe, can now be heard from 7 p.m. to midnight weeknights on the classic rock formatted station.Griswold, who is also Galaxy Communications' vice president of programming, was a midday mainstay at the station before Dave Frisina joined the ranks from 95X (WAQX) in April. Mimi's new voicetracked shift replaces Roger McCue.
