Cover art for Olives lyrics by Devin Townsend

I am rather certain that this track is a reference to Pink Floyd's The Wall album; notably the final (and inter-connectedly, the first) tracks. "Isn't this where... we came in" is a line looped between the end and beginning of the album. The backing audio is very similar to Olives, which I believe pertains to the similarity, as well as Devin's line "Come in".
