Wow, Sweet Dick Burch...he made an impact for a while in '72 and '73 at WHEN, but he broke not one, but two contracts in a single year.
First he jumped his WHEN contract, IIRC in the spring of '73, for more money at WNDR.
Then he bailed out on WNDR a few months later when NBC O&O WMAQ offered him a job there, thinking he'd do for them in Chicago what Don Imus was doing for them at WNBC in New York. At the same time, maybe to keep collecting WNDR's money and maybe to avoid yet another lawsuit, he tried to double-dip and fulfill his WNDR contract by voicetracking his show for 'NDR and continuing to collect their money, while doing the live show in Chicago. (It had to be one of the first voicetracked shows in upstate NY in 1973-74, and it SOUNDED taped--I don't know where he cut the voicetracks, probably at WMAQ, maybe at home, but I heard he was somewhat spotty in supplying them and a lot of older jokes kept getting recycled whenever the new break tapes were slow in arriving). I got to Syracuse during the late summer of '73 just after Burch jumped WHEN, and in the halls at 980 James St. they couldn't mention his name without attaching a cussword, until the fall '73 book came out--and we found out how little had really been lost.
Turns out all that turmoil only worked out for Sweet Dick's bank account. 'NDR didn't get great numbers once it became known around town that his show was canned goods, and he didn't score well at 'MAQ against veteran Chicago personalities like Wally Phillips, Fred Winston and Larry Lujack. He didn't put a dent in either WGN, WLS or WCFL. Meanwhile back in Syracuse, Phil Markert--who was definitely live and increasingly uninhibited--was pulling numbers every bit as good and better than Burch did for WHEN right from the start, and kept on building.
WHEN ended up getting the best of the bargain when all was said and done.
