Irish tunes are not often crooked, the style being more closely married to general dance types that require a square meter. But here's one, perhaps composed in order to trip some dancers.
The reel is called John Doherty. John Doherty was a Donegal fiddler and I'm not sure if this is a tune he wrote or not. This tune is crooked because it has a half-measure after the second bar, so the counts go 1-2-3-4-5-1-2-3-4 (2x) in the A part.
