I don't know the answer to your question, but that never stops me...Last night I was listening to the Papa George blues band (Sam Kelly on drums and Pete Stroud on bass) with special guest on keyboards, Roger Cotton, who played one solo on "vox humana" (I guess) which sounded like someone scat singing like Slam Stewart. At one point in another number he hit the wrong control and got a dog bark which made all the band jump and then hammed it up pretending to look for the dog!
