There is one John Lennon song out of 165 songs on that list. Are you sure that is the reference?
I suspect so, because the existence of that list got a lot of press at the time, and I think the presence of "Imagine" on the list got attention in its own right. So I think this list is likely what people would be thinking of in that context.
