Blended Scotch For More Than Scotch & Soda

Looking up stuff in the PDT book, I found a cocktail called the “Professor” using rum, port and sweet vermouth. I noticed in the note that it was a variation on the Chancellor cocktail, so I looked up that (I have a thing about rum, which is my own problem) and found this: four parts blended scotch, two parts port, one part white vermouth and two dashes orange bitters. As the link notes, scotch is an odd cocktail ingredient, but this was good . . .
