Robots sitting in with other bands?

I saw a 2010 video of Phoenix playing at MSG & during Encore the robots came out and played a few songs and jammed??? I was 20 then & a huge fan but do not remember them touring much after the ALIVE years?? Are there other pop up appearances they did like this out there??
