You're right, any Plemmons production is good production. He was a production guru. As for him working afternoons 81-82, I can't say for sure. I thought Hunter was afternoons then. Maybe not, but then, maybe Plemmons was filling in for him.
Regarding Tom Kent, I can't say a whole lot of bad things about him. I know he didn't get how the Columbia audience responds and what they respond to. But, he did hire me the day after Frank Baker fired me at Z96 for missing an announcers' meeting(I had an exam at Carolina...but that's another story for another time...lol). After Hunter quit, TK moved me to 6p-10p and made me the music director. It was the very first time someone trusted me in a leadership capacity in radio(only MD, but it was a start)and I learned a LOT from TK and from having the position. Two months later and TK was gone and I was the afternoon guy. Crazy how things work out sometimes, you know?
Incidentally, when TK was there, Phil Gardner was doing mornings, Pandora middays, TK from 3p-6p, Hunter 6p-10p, me from 10p-2a and Jimmy Duncan from 2a-6a. When Hunter left, I moved to 6p-10p and TK hired John Rocke from Z96 to do 10p-2a. When TK got fired, I went to 3-7 and Rocke went to 7p-12 mid with Jimmy doing mid-6a. I think Phil Gardner stayed for awhile(until trends came out) and they got rid of him. Phil was a class act about it, tho. Hell of a nice guy.
It was when Pete Hamlett became PD that they hired Jay Jay to do middays, moved Pandora to mornings with Leo. They moved Mark to mornings, too and VOILA! it became the K-Team Morning Zoo.
The rest, as they say, is history.
