Don't know if i'm hearing things, but if people remember Charlie Brown was originally being played with or on accordion when Guy stepped in and said this is too much (Thanks Guy) - anyway, listening to it, and i think they left some of the accordion on there, listen closely after sped up vocals start, and the guitar riff builds up, and before the drum comes in.

 

I think they left in the accordion as a homage to the original roots of the song, listen closely in the first 20s or so

I believe you are correct sir :D

Yeah it was with an accordion initially as part of that story/film thing they started doing. I'm not sure about the accordion being in the studio one, i'll let you know my thoughts when i've listened to it again!
