Wesley Willis, P.I.
 
Wesley Willis was an American singer-songwriter and visual artist from Chicago. Diagnosed with schizophrenia in 1989, Willis began a career as an underground singer-songwriter in the outsider music tradition, with songs featuring his bizarre, humorous and often obscene lyrics sung over the auto accompaniment feature on his Technics KN keyboard.

I think he should also solve crimes.
