Amen to all that and more. Jack is a gentleman, an accomplished voice talent, and a very nice man. Our paths have crossed few times over the years, but I've admired his work and his personality for over five decades.
BTW, I've always heard he had a memorable on-air resignation from WMC the morning they put the country format on in his show. I heard he played a song and said, roughly, "That was Johnny Paycheck on WMC and, speaking of paychecks, I'll be picking mine up a little later this morning." Is that anywhere close to the truth? I've always hoped so. If it is true, I place Jack a very close second to Fred Cook insofar as integrity is concerned...and there's no one I've ever known who has more integrity than Mr. Cook.
