I don't wish, I know it for a fact. Go to Africa and see if any tribes are playing blues. You'll see there are none.  :roflAfrican Blues. No, you won't hear any of that deep in darkest Africa. But there are some pretty damn bluesy Irish and British Folk songs that date back hundreds of years..and so-called blue notes are very prevalent in much traditional Irish and British music...coincidentally, only pure coincidence;)     Oh and the first known and first published and copyrighted Blues song/composition in history... was called Dallas Blues by Hart Wand back in 1912. It was a piano blues, it was a huge hit at the time and was played in bars and honky tonks all over America. Hart Wand was a WHITE, German-American fiddle player, pianist and composer/songwriter from Oklahoma... It was the first known song in history to use Blues in the title and to utilize all blue notes. The first Black man to release a song/composition with blues in the title and utilizing all blue notes was a full TWO YEARS later, it was WC Handy from Memphis, the name of the song was St. Louis Blues and he had the nerve to bill himself as the Father of the Blues even though a White, German-American from Oklahoma beat him to the punch a full TWO YEARS earlier! :D
