Re: Quasar doing "wonderwall"
Intergalactic was an older song which they took off the shelves for Hello Nasty. There is a story on that in the book that came with the Anthology album.
However, a year in avance seems like a long time. On the other hand, the parts of the video apart from the rapping in the streets may have took a while to create. And Intergalactic was the first single off Hello Nasty (perhaps even released before the album?)
