By “funeral” do you mean that some sort of service is taking place at the local crematorium? If so, have a word with the funeral director. Crematoria have access to some sort of music library and they’ll generally acquire whatever is requested so you don’t have to track down a recording yourself. They had no problem getting hold of an obscure Sarah Jarosz piece for my mother’s funeral.

The only version of Inch by Inch I’m aware of is the Arlo Guthrie version - I have the vinyl ….. somewhere!
