Plus Lightspeed Champion is added to Morrisseys Hyde Park gig
They will all support Morrissey when he headlines Friday July 4 at the London event.
Also joining the former frontman with The Smiths at the Hyde Park gig are punk legends Siouxsie and New York Dolls.
Already announced are Beck and The National.
Other Wireless dates are headlined by super-DJ Fatboy Slim and US rockers Counting Crows.
Last week Morrissey said of the event: "I will take Hyde Park like a flea inhabits a dog. Art-hounds and people with badly cut hair are very welcome." Tickets are already on sale.
