I read somewhere that Seige of Ennis is a comparativly new dance introduced during the gaelic cultural revivals early in the last century. It may be the tune of that name and dance arose separately. The Seige of Ennis appears in two-four (polka?)time in the Roche collection, published in 1912 and it is a great tune to dance to. Last time I heard it at dance, where the violinist was none other than Matt Cranitch, I am pretty sure in was in that neter. But I can't be certain, because it was a step I didn't know, and was going to sit out until whisked on to the floor by a stunningly beautiful young viking-looking lady from Limerick who I never saw before and never since. Maybe I dreamed it all anyway!
