"And then I think they asked me to work on Wish You Were Here, which was the next album coming up. And I didn't do anything for a long time. I had other projects, and I didn't get around to doing anything for a bit"

Gerald Scarfe was asked to work on the album Wish You Were Here, but he didn't right away begin working on it. He had other jobs that he was working on and he didn't get around to doing anything for the album for a while. This could be translated as Scarfe being hectic with other tasks and not having the time to dedicate to the album, or it might be translated as Scarfe not being interested in the project and not wanting to deal with it. It could likewise be interpreted as Scarfe being reluctant to begin working on the album, as he was uncertain of what he might contribute to it. Whatever the factor, it is clear that Scarfe did not instantly start dealing with the album, and it took him a long time to get around to it.
