Hallmark had a "Murder, She Wrote" marathon over the weekend. The first two seasons were aired in episode order.
What stunned me was the series opener -- a two-parter entitled "The Murder of Sherlock Holmes' (IIRC). That wonderfully jaunty theme for the show was written by Oscar-winner (for "Tom Jones") John Addison. I hadn't realized that Addison scored the entire two-parter and won an Emmy for it.
It's delightful, and it's easy to hear the difference between his use of the theme throughout the two-part opener and the subsequent referential use of the theme by other composers in subsequent episodes.
It's a score, that opener, that ought to be on CD!
