Vivian Stanshall solo - C or D; S & D?

Just interested in people's opinions on the Great Man's solo work... Surely no one doubts the sublimity of the Bonzo Dog Band and Stanshall's part in that, but do people like his solo work?

Myself, love it just as much really, from what I have heard, which is:
"Sir Henry at Rawlinson End" (1978) - need I say more than the title? It's a gloriously insane world, all beautifully relayed by Viv in his enveloping tones... the use of language utterly inspired; perfect musical backings and sideshows. "Teddy Boys Don't Knit" (1981) is a real grower of an album; presence of many effective guest players helps, and Stanshall's on fine form. There are many wonderfully punning and jesting upbeat 'rock' (the genre is always twisted in some way) numbers. Most tellingly, "The Cracks are Showing" (with IIRC a harmonium and wistful barber shop harmonies as stark backing) and "Possibly an Armchair" are two of his saddest, most personal songs. They are the match of "Sport (The Odd Boy)" and other more reflective Stanshall Bonzos songs.

And that's as far as I've got with his back catalogue; not all is in print, I know. How do people rate the above, and other Stanshall albums...? "Men Opening Umbrellas" I have heard fleeting calls of praise and much clamour for re-release. I wish it was released, and I wish that Vivian Stanshall was a more well-appreciated figure.
