Everything done in a pub or bar with attitude is punk. That's where punk comes from. The Beatles were doing mach shau punk in Hamburg in the early 60s. I do a punk version of "Wreck" as well as punk versions of "Man of Constant Sorrow", Folsom Prison Blues", "Iko Iko", "Sweet Caroline", "Cecelia", "Brown-Eyed Girl", "Mustang Sally", and "Roadhouse Blues", amongst others.
