I am indeed conected - in fact I am the same person - and I got some useful names from that thread.
This one on the other hand is proving hopeless!

Let me try again!

We are organising a free public event in central London in June with several dance actvities already planned and a big audience expected.

However, in my opinion (please dont lets debate this - thats not why I have posted) most of the music accompanying dance teams is pretty insipid. Its usually unamplified, much too quiet - and its often very dull.

Ceilidh Bands on the other hand are great, and we hope to have two of them as well - but they need a static PA system and a stage.

So what I'm looking for is a group that sits between the two (a bit like the strolling jazz bands, samba bands, brass bands etc). I don't mind if they come with a dance team - and I don't care what sort it is - thats not my main priority - what I'm after is the music.

Yes I can pay a decent fee.

Can anyone suggest a couple of names?
