The fine writer-director Vince Waldron writes and directs my attention to this article in which Dave Thomas, who played Bob Hope on all those wonderful episodes of SCTV, talks about getting inside the man. (As Vince notes in his e-mail to me, the article is wrong to call Thomas a "founding member" of Second City but the piece is otherwise very good.)
And since I'm invoking Vince's name, I'll mention that this month's performance by his improv troupe, Totally Looped, takes place this Saturday, August 9, at the Second City Studio, which is on Melrose right next to Budd Friedman's Improv. Starts at 8:00 and the last one I attended made me laugh an awful lot.
