Looking up some background on Stan Worth, the orchestra director in the later seasons of the 70s run of "Name That Tune," I found that he died on August 31, 1980 in the crash of a private plane that he owned. Would production on that year's NTT episodes have already wrapped by that point, or did they need to find a new conductor?
FWIW: Born March 29, 1932 in Norfolk, Virginia as Stanwurt Valentine Schilling.
