More than anything else, except perhaps their music, Abney Park is famous for their onstage screw-ups. In fact, it is generally considered an undeniable truth of {{steampunk}} venues that something will break down, give out, fall apart, distort, backfire, ignite, explode, or generally mess things up during the Abney Park set.

* From their Creator/{{G4}} special: "Is that on fire? I'm not wearing that if it's on fire... It's smoking, that means it's on fire."
* [[http://www.youtube.com/watch?v=AAwtpCLqQcI "PARKING METER!" "SPANDEX!!!"]]
* At one concert, Captain Robert's microphone handle snapped -- in the middle of "Aether Shanties," right on the cue of "The ropes creaking, ship's leaking, sails are on fire / And this whole bloody ship could go up like a pyre". And, well...
-->"We're giving a steampunk concert. And ''no one'' has a screwdriver?"
* At a convention where some badge ribbons had been given out (one of them said Accordion Hero) the Captain's accordion strap broke.
-->"Room full of steampunks and nobody has duct tape? Now is not a great time for the 'Accordion Hero' award."
* Their remedy to a classic onstage mishap: When the lead singer screws up, [[http://www.youtube.com/watch?v=bloSdPhViVE blame the]] [[NobodyLovesTheBassist bass player]].
** From the same show:
-->'''Robert''': Here's another point about my life: Nathan's a really nice guy. He's not always right -- but he's always really effin' nice.
* At [=DragonCon=] 2009 they attempted to play the classic flying-car song: "Chitty Chitty Bang Bang." After two false starts, they stumble through it, ending more or less on their feet, until their violinist goes up to a microphone and says: "What could we possibly play after ''that?!''
*** There was also the mid-song banter between Captain Robert and Jody:
-->'''Robert''': "We've only practiced this song once."
-->'''Jody''': "That's one more time than we practiced the rest of the songs."
*** At least they got it right at the [[http://www.youtube.com/watch?v=cDTdReXW9po World Steam Expo]].
* And who can forget the "Airship Pirate" fiasco -- the night Captain Robert forgot the lyrics to their most famous song: "Airship Pirate."
* "Those of you who saw the [[http://www.youtube.com/watch?v=CRU93GzhFas epic hungover "Rainbow Connection" performance,]] treasure it, 'cause it'll never happen again."
* At one concert, Robert related the story of one time when he accidentally hit himself in the head with his drum mid-song during rehearsal. Cue Nathaniel playing sappy music on his violin to accompany Robert's tale of woe.
-->'''Robert''': Are they buying it?
-->'''Nathaniel''': *(pauses, then starts playing "The Irish Washerwoman")*
-->'''Finn''': I'm sorry, not tonight.
