please recommend your favorite blues/romantic songs for me. two friends and I are planing on forming a band,we intend to sing in restaurants and bars in the south of Rio de janeiro and intend to sing only in English. I know a lot of songs myself but most of the ones i know popular ones but i would prefer not so popular ones or if you have link/address to a site where i can find list of good but not common blues, please drop it. Please dont just pass by without recommending a song

This is are examples of songs we need. Thanks.
