I can tell you that Andrew Sachs also plays a mean cockney gangster as he did in the Meet the Magoons pilot that i recorded for Channel 4 back in '04.And in further Fawlty Towers news -https://www.aucklandlive.co.nz/show/fawlty-towers-live
Ginger Baker just played what might be his last performance.http://www.elmoremagazine.com/2016/11/music-news/ginger-baker-honors-jack-bruce
I would love to see that Fawlty Towers live show.I saw a short video of him speaking at that event, he seemed weak and unsteady. Sad but not unexpected, since he announced he was in bad health.
