Also coincidentally been watching the latest Stewart Lee
https://youtu.be/X1UCt5iItcw
(which also features Alan Moore interviewing Stewart, as a framing device)
And last night found.. in Doomsday Clock issue 3..
Stewart Lee depicted onstage in the sequel to Watchmen, getting bottled off in The Joker's bar in Gotham

Now Doomsday Clock has nothing to do with Moore or Lee and this move by DC has probably really aggravated both of them
- but,
nice touch :-)
