I'm not 100 percent certain he's the guy you're looking for, but there is a Glenn C. Lewis who is a high powered and expensive divorce lawyer in the Washington DC area. Google his name and you'll see what I mean. Glenn C. Lewis did a cable TV show about divorce law some time back, so he could be the same guy who was at WROV in the sixties. A good many lawyers started out in radio.
On the subject of that name, I worked with a Glenn Lewis at the old NBC Radio News and Information Service (NIS) in the mid 70s. Lewis was one of the anchors of that early and ill fated effort at continuous radio news 24/7. It folded in 1977 because so many NBC affiliates wouldn't carry it, and NBC couldn't figure out how to sell it to non-affiliate stations.
Along with Glenn Lewis, we had people like Cameron Swayze, Ann Taylor, Cliff Barrett, Charles McCord and others sharing the anchor duties. I was an editor/writer, chained to my typewriter on the writing desk.
I know Ann Taylor is now with NPR, and McCord worked with Don Imus for years till he retired a few months ago, but does anybody know what became of those other anchors?
