is "in the past and now" a commonly used collocation? For example, are titles like these correct: "London in the past and now", "Life in the past and now" etc.
A Google search currently gives me 184 results---it can be found, but it isn't common. It's more common to collocate two terms that are grammatically similar to each other, such as:
- Life in the past and present
- London yesterday and today (implies a broad meaning of 'yesterday' that can cover past decades)
- London then and now
