I've often thought that the over orchestration and dramatisation of his work during this period was to make up for a lack of decent lyrics.
Neil's best songs do have a certain drama to them but they developed into melodrama for a long time. Yes Solitary man is probably better than September Morn...but I was listening to the original recently on the dreadful September (contractual filler) Morn album and it's damn good. OK it could do with a bit of a tone down...but it's a fine song.
Now there's an album, September Morn, that should've been killed at birth...truly dreadful. Perhaps I should temper that by saying..not to my taste.
