Leafing through an old magazine at coffee time I saw two cartoons by the same hand one of which fits here and the other can be shoehorned in!
One showed a "two-tone" band all shades and porkpie hats. The leader is saying: "Unfortunately all the black players play like white guys. Fortunately, all the white players play like black guys."!
The other showed a guy being chased by another (shades, porkpie hat) wielding a guitar like an offensive weapon. He is saying:"I thought I had the blues, but apparently I'm just a psychotic schizophrenic".
