I shot this video of Yo La Tengo on my trusty PXL-2000 camera. Not sure what the song is called. Buy "Prisoners of Love: A Smattering of Scintillating Senescent Songs 1985-2003"
UPDATE: according to @bourgwick on Twitter the date is "june 29, 1991. end of mcnew's first proper round of touring with YLT." & according to my friend Sean Howe (Author of MARVEL COMICS: THE UNTOLD STORY) "It's called "Swing for Life"; it first appeared on a 1991 EP."
