Like most of us I'm sure, I dance a lot less at gigs now than I did in "the old days".
I do however dance* much more at gigs than anyone else I know, which annoys the pants off most of the people I go to gigs with!
Recently, the Wedding Present at the Wedgewood Rooms in Portsmouth was a belter. Lots of elbows and uncouth jumping around..
The Cramps at Hammersmith Palais takes a lot of beating. Two occasions, both exhausting.
Otherwise, I'd have to say the Bhundu Boys were superb for dance-oriented gigs. Specially in a little club upstairs on the Cowley Road in Oxford, whose name temporarily escapes me
*I use the phrase in the most general 'moving about' sense!!
