When I first read this I was inclined to give them the benefit of the doubt, and to think that it was just a case of over-enthusiastic marketing of a genuine band. although the reluctance to fully identify the musicians on the website raised my suspicions. However having re-read some of Adam's posts (and assuming they are genuine) then I think the OP was right - this seems to be just a front for a network of scratch bands. Adam's claim that they use deps "more efficiently" than other bands as good as admits this.

Of course there is nothing wrong with using deps, and most bands use them from time to time. However there is a difference between bringing a dep into an established lineup, to cover the absence of a regular band member, and sending out a scratch band. There's nothing wrong with scratch bands either, provided they can deliver the goods, although to claim that a scratch band is better than one which regularly rehearses and performs together is extraordinary. However it's the lack of honesty which is disturbing. Fraudulent? probably not, but undoubtedly misleading.

Of course it is clearly aimed at the wedding market - nothing wrong with that, this the bread and butter for most bands. If the lineups they send out meet the standards of the examples on the website, I'm sure they do a good job, although I don't see anything to support their claim to be "the UK's premier ceilidh and barn dance band". They seem to have only contempt for the folk scene, but they're entitled to their opinion. However they should bear in mind that couples booking a band for their wedding often want more than "testamonials" - they do their due diligence, and often want to see the band perform before deciding to book them. That might just be a problem. The band also might like to consider that this thread will no doubt come up on Google searches, and will reveal not only what they are up to but that Adam's responses show they are arrogant and condescending - all of this is likely to put off potential clients.
