Alfred P. Morgan, known by the stage names Big Benn Klingon and Benn Grimm, was an associate of MF DOOM and was credited as an executive producer on the 2004 album Mm.. Food, and later his tour manager and hype man. He can be heard throughout the Expektoration live album.
His Twitter has been inactive since 2015, and his Instagram is private, so it’s unclear what he’s up to these days.
