Now the singer has doubled down, canceling a planned appearance on tonight's Jimmy Kimmel Live because cast members from the Louisiana reality show Duck Dynasty also will be on Kimmel:
Morrissey says he can't perform on a show with what he called people who "amount to animal serial killers."
A&E's Duck Dynasty reality show follows a Louisiana family with a business selling duck calls and decoys.
A&E did not immediately respond to requests for comment from it and the Robertson family.
The appearance has been rescheduled, and surely Kimmel will ask the Robertsons about it tonight. In the meantime, read Lauren LaBorde's 2012 interview with Duck Dynasty's Willie Robertson.
