Retired to his horse farm outside DC and reported to be enjoying life in retirement. He left music radio wayyyy behind when WABC let him go in 1979, and built a national rep as a sports anchor and commentator.
There are those who've said WABC management initially didn't plan to make Michael a part of the so-called "Thanksgiving Day Massacre" in 1979 that also booted Harry Harrison and Chuck Leonard, moved Dan Ingram into what he later called the "dark tunnel" of the morning drive shift, and Bob Cruz into afternoons. But Michael was clearly moving out the door of MusicRadio 77 into the sports radio/TV realm--he was already taking some nights off to work NY Islander games and handling weekend sports anchoring duties at WABC-TV. He is said to have asked for enough time off to be a fulltime part of the NY Islanders broadcast team--which, given that the Islanders were in a long and successful multi-season playoff run at the time, could have taken him away from WABC for close to half the weekday evenings of the year. That was too much for WABC to handle. So out Michael went along with Harrison and Leonard, to be replaced by Howard Hoffman.
Michael has said he had no hard feelings toward WABC because by releasing him, they freed him to do all the sports broadcasting he wanted to do--and he made a good 25+ year run of it.
