Anon. here (now with wine and cookies - just like the Pilgrims ate).
So, before I left for work this morning, I saw a tweet from a guy who works at Radio 2 telling TH to check out a country music program. Turns out it featured a song from the ISTL soundtrack: Why Don't You Love Me. Or as I call it, The TH and EO Post Pap Night Question Song.
It starts about the 49:40 mark in the show.
Interestingly, they apparently recorded the soundtrack using equipment available during HW's lifetime.
I think he sounds sufficiently 'country.' He's twangy, for sure.
