If anyone is bothered what PVFH stands for, it is a title abbreviation of the song "Precious Voice From Heaven".
Given the age of a protagonist is specified (42) and the circumstances, it does suggest specific person and the point in time.
Yes that's my point. If he does so, it is "unfair" to not give a hint that makes it easier to work out who it might be. I know a songwriter owes nothing to anybody but if I guess it should be POSSIBLE to work it out for a listener.

I suspect it is about Dylan.
At the time of "Infidels" (1983) Dylan was 42 and Mark was involved into recording.
There is a note I found on wikipedia about recording of "Infields":
"
Dylan initially wanted to produce the album himself, but feeling that technology had passed him by, he approached a number of contemporary artists who were more at home in a modern recording studio. David Bowie, Frank Zappa and Elvis Costello were all approached before Dylan hired Knopfler"
Dylan does wear a kind of Trilby Hat...

Somehow I believe "Lights of Taormina" is also related to the companionship between Mark and Bob. I would not suggest what a kind of.
Taormina is well known as a gay friendly destination
https://en.wikipedia.org/wiki/History_of_Taormina (read under the "Gayheyday"). Even the lyrics in the song suggest so:
"
They were young and love was shining
Like the colours of the rainbow"
In both songs, (albeit disgusting would it be the case if you ask me), you can just think there is no girl at all...
(but you are open-minded, no?)
