"They are monopolising the web, preventing any other ceilidh band getting gigs, and thus slowly strangling the ceilidh band scene."

A bit of an exaggeration, though I'm no apologist for their marketing methods.
Anyway, I tried ceilidh Band Cambridge on Google and the Ship band only appeared as the second of two paid Google adverts, under London-based Licence to Ceilidh. My own band appeared third in the proper listings under the adverts, and we get enough work without having to pay Google for the privilege. (insert smug grin emoticon here)

Interestingly about half way down the page was an outfit described as "Cambridge-based band... drawing from a large pool of local talent". At least they are honest about what they do. The Cambridge University Ceilidh band is similar, being capable of pulling together two or three separate bands on the same night if lucky.
