I was listening too the first of the three filmore shows the other day, and during the outro of one big holiday, i swore i heard Jim play the outro mandolin lick of REM's "Losing My Religon" as the last lick of the song. I took a listen to the REM song again and im pretty sure its dang near the same thing. Take a listen and tell me im not crazy.

Ok, I've just listened and it is there. Very similar at least.
I declare you a sane man.
