Yes, I know, no vocals. But its lead off tune "Chitlins Con carne" did make it into the repertoire of 'real blues' groups like Jr, Wells' and Jimmy Dawkins'. And I've found many blues fans do enjoy stuff like this, and Jimmy Smith, etc. as well as Muddy Waters, et al. And some don't - but then not all blues fans like the same indisputably blues singers. And the very concept of 'blues singer' has been questioned by some too.
