Does Anyone Remember the Brown University Band From the Mid-Seventies? (Providence)

Hey Bipeds! I grew up across from Brown and now I’m great friends with a guy who graduated from there in the mid-seventies.
He played in the Band and just mentioned that they used to play a dirty version of Charlie On the MTA, but he doesn’t remember how it went.
His 65th is coming up, and I thought it would be a trip of a gift if I could find those lyrics.
Or, if there’s any video kicking around of the Band playing the song, that would be so mint! If you have anything like that or know where I can find it - other than, you should call Brown - feel free to email/text.
Thanks, CL Community! -Becca
