David beating Goliath. It appears likely that WGRV, which now plays soul music oldies, will switch to a format identical to WNIC's soft rock to get Harper's cadre of listeners to come along. A call letter change would follow. Harper's departure is a major blow to WNIC, which until this month was the overall listener champ, according to Arbitron. Harper, a Detroit area native in his 40s, has worked in the market for 30 years, alone or with partners like his current group and earlier with Jerry St. James and Steve Gannon.
