It is interesting to see how Mitch did or did not get involved with pop/jazz crossover projects. For example, he arranged the (excellent) Other Voices LP for Erroll Garner, certainly a crossover artist at the time. Mitch was apparently not involved with Johnny Mathis's first jazz LP for Columbia, produced by George Avakian; but after Mitch took over and moved Mathis into more of a pop direction, Mitch wiped the tapes of the unreleased tracks from those early jazz sessions - a full album's worth of tunes. I would love to hear these, but they are gone. Mitch didn't understand why Tony Bennett wanted to do a jazz-leaning album for his Columbia 12" LP debut, Cloud 7, but allowed him to do so. My copy of the LP does not credit a producer.
