He used to drink champagne wherever he went, it is mentioned in the book the "The Brotherhoods." He was killed by Sal Miciotta, Sal thought he was ordered to kill Larry because he was messing around with another wiseguys girl, but it was over the mafia gasoline tax scheme. Larry Champagne was said to making big money from it, and other mobsters wanted that money.
According to Michael Franzese's book Quitting the Mob, Champagne Larry was ordered killed by Sonny Franzese because Champange Larry fooled around with Sonny's Daughter and got her hooked on coke (and Larry was married at the time). Will be interesting to see how the TV portrays it.
I might or might not be related to a former Zip boss
