Being a gullible American,I imagine your idea will work quite well, providing you keep the songs something short of 26 verses. I am assuming you are being somewhat facetious with the "gullible" tag, but if you are entertaining and informative,I would imagine folks would buy your services. I travel quite a bit and frequently hire private tour guides in areas where I would like more information than is readily available. I hope these people that I am paying money to don't necessarily think of me as being a gullible American. Most of the folks that would meet that description would not be interested in hearing any traditional music anyway. They are all shopping at Harrods' or at Speakers' Corner for a photo op with some nut job on a soap box. Good luck!   jimmyt
