English fiddle music is decorated, decoration does not have to interfere with dancing, in fact it should not.
Alistair Anderson manages to play for dancing and uses decoration, and so did Walter Bulwer.
It may not be as decorated as SOME IRISH MUSIC, BUT it does use decoration, Irish music uses decoration and is in my experience as it is played in Ireland still danceable.
I see people dancing regularly to irish trad music.
