9 months after Wally Brine retired, WROR still has the Loren and Wally Morning Show. With Loren, Hank, Lungboy, and LBF...but no Wally. Wally still pops into the studio on occasion. You can still hear Wally voiceovers. They still run Men From Maine (with Wally and the also previously "retired" Tom Doyle). They still do the occasional Wally's Records From Home Weekend.
How long can they run a Wally-less Loren and Wally show? I guess as long as they want for as long as they remain number 1 in the ratings.
