The Caesars got Iggy Pop to record a vocal track on an updated version of their old song "Punkrocker" which first appeared on the 200 album "Cherry kicks" which they released back when they were still working under the name Caesars Palace. No word yet on where this new song will appear, but I'll keep you posted.
UPDATE: I guess this is for the upcoming Teddybears STHLM album that's coming out in the US sometime next year. I heard some word of a bidding war over these guys, so I guess some sort of deal came through. More details to come.
