I've been listening to a load of MDC at the moment and decided to take a look on their wiki page. I was STUNNED to find out about this whole argument regarding Big Brains.
For those who don't know it...
During the summer of 1982 they became involved in the Rock Against Reagan Tour, during which time they fell out with the band Bad Brains when Rastafarian singer H.R. learned that Big Boys' singer, Randy Turner, was gay. H.R. and MDC's Dave Dictor had an intense confrontation. Upon Bad Brains' departure from the bill, they refused to return a loan owed to Big Boys and instead left a note that reportedly read, "burn in hell bloodclot faggot." The incident resulted in the MDC song Pay to Come Along. For MDC, 1982 ended with a tour of Europe with the Dead Kennedys which brought the band greater exposure in the punk scene outside of the U.S., especially in the UK.
Always a bummer when a band you love turn out to be total cunts
