I've heard talk of Garrison Keillor retiring, but it hasn't happened yet. But he wasn't there this past Sunday as I drove home from church or as I fixed and ate lunch (WFAE does it live and then after the rerun of "Wait! Wait!"). It just wasn't the same. Without Keillor's voice, it just doesn't seem like the same show. I know it had the funny sound effects and music that may or may not be good depending on my particular taste, but if the man does retire they should just do reruns.
I've never listened to the whole show but I do like what I hear.
