One who is addicted to Polka.
The Polkahollics are a band from Chicago weave an interesting blend of polka and good ol' rock 'n' roll. The band is lead by singer/guitarist Dandy Don Hedeker, with Action Jackson Wilson on drums and Jolly James Wallace on bass.
Their polka-rock mix has culminated in one of my favorite songs of all time:
In heaven there is no beer
In Heaven there is no beer
That's why we drink it here
And When we are gone from here
Our friends will be drinking all our beer
