I remember quite clearly that shows would record their cast albums the first Sunday after the opening. The albums were in the stores by the Wednesday or Thursday after that. It was rare for a show to wait for weeks after the opening to record their cast albums. And rarer still to record the album months before the opening as Oliver did. I can't think of an instance before Oliver when that happened. Today, it can be weeks before the recording is made and months before the release. One would think that things would be faster with the new technology. Alas, not so.
