is there a band named this except with a different name before city blues?

EDIT: I need to know for copywrite info.

it won't be infringement unless you end up using something that someone has in the blank, which i know sounds obvious but theres a good chance what you're thinking of is not taken. you wouldnt be infringing with just using ___ city blues, you'd have to have the first part right too.
