Otherwise this was a sweet play about two damaged men in love. Walliams was muted, apparently weighed down by the responsibilities of impersonation- and Rafe Spall as Howerd's lover/chauffeur/manager was lively and engaging. At times I wished the two actors had swapped roles.
Why were all the comics of that generation such wrecks? Is it something to do with the war? With the aftermath of war? With the profound social changes of the 50s and 60s? A theory is hovering- just out of reach- and I haven't been able to net it.
