This is a bit of a deep cut/long shot, but there is a moment from the WFMU show in which Tom talks about going to a BeatleFest/Beatles convention.
Over the years, there have been a handful of BeatleFest discussions, but the one I'm trying to find is prior to 2011, and it contains the following:
Tom tells a story about some guy (I think an older guy) who wanders from the Beatles jam in a hallway/lobby area, into an area where they are screening a film. The guy has an instrument (I believe a harmonica), and he starts playing along with the film being shown.
I cannot for the life of me track this episode down. If you go into the archive and search "Beatle," you find two relevant-seeming descriptions:
April 8, 2008: Tom Breaks Down His Sad Visit To The BeatleFest And His Defeated Quest For Bootlegs. Bryce Calls In To Talk Bootlegs. Pudge Throws His Hat Into The Ring. And The Topic Is 'Losing Your Cool'.
March 27, 2012: MATT WALSH discusses his new film ‘High Road’, and TV show ‘Veep’! KURT BRAUNOHLER talks about subs! Casting ‘The Best Show Apprentice’! Tom went to another Beatles convention, and things got weird! And a little taste of ‘The Vance and Gary Show’!
^^^However, neither of these are the show I'm looking for.
It is also NOT the March 29, 2011 show with the "Mr. Moonlight" story.
I know this is a longshot, but if anybody happens to know how I might find that episode, I would be so appreciative!
