According to Norman Barber (A Century of British Brewers Plus, 2005, page 83) the Cannon Brewery was bought by Taylor Walker in 1930, but continued to brew until 1955.
Which is surprising, given the brewery's location in Clerkenwell on a very cramped site. Even more surprisingly, part of the brewery is still standing at 160 St. John Street. One thing that does live on is their Cannon logo, which was knicked by Taylor Walker.
I'm continually amazed at just how long some breweries clung on in very hemmed in central London locations. It must have been a nightmare getting raw materials in and beer out.

Straight off you can see that they didn't have the clarity problems that Barclay Perkins did. All but 2 out of 14 were bright. Or maybe they just trained their landlords better.
Only four have negative scores, which is also pretty good. Though none of the examples was excellent and there was one really bad one. Given that some of the examples are 10 gravity points weaker than Barclay's X Ale, that's fairly impressive. Or are Barclay Perkins negatively impressive?
Whatever, they average out to a positive score. I'd give their pubs a try, possibly. Though I'd prefer something with a little more poke.
