The Bad Shepherds play punk songs on folk instruments. Not as a gag, but because they really like the noise. They think the songs are better than people remember. They love folk instruments. It works. They do songs by The Sex Pistols, The Clash, The Stranglers The Jam, Sham 69, The Undertones, Talking Heads, Squeeze and others, even Kraftwerk! Alright, they're not all punk, but they come from roughly the same era.
