On ONE occasion , I booked a band on the strength of a Cassette they had sent to the club - I Five piece Irish style band that sounded VERY good ! On the night , they were a Four piece and only TWO of the four had played on the Cassette , and none of them were'singers'
This was iun the 'Good Old Days' before Internet and U Tube etc !

But I agree that this thread is NOT a good idea !!
