The Kay-Settes starring Butchers Blind

Obscure band of indeterminate genre in the song "The Late Greats" by Wilco on their 2004 album A Ghost Is Born.

The best band will never get signed
The Kay-Settes starring Butchers Blind
So good you won't ever know
They never even played a show
Can't hear them on the radio

The song mentions another band, The Late Greats.

A real band named themselves Butchers Blind, after the song lyric.
