We play "Blister" all the time... it's hillarious... With no intro at all, with no warning, at any point in our show we can play the first 16 notes, and automoatically the audience hits the table "Da-da! Da-da!"

I assume the song in question however is "Kiss Off"
( - Lyrics Here - )

and I found all kinds of copies of it with a quick Kazaa search... so it's that easy to get...
