Not quite the same, but it's cogent.
There was a one-man show done by Hal Holbrook entitled "An Evening with Mark Twain." Twain died in 1910. Holbrook was stunning in his portrayal. It was really like being with Mark Twain. I recall the scene where Twain said, "Congress. That benevolent old asylum for the helpless."
I have never gone to a show done by copy bands. The few I have seen on TV were disappointing. Hell, there's a commercial late at night that has some guy from Sha-na-na and it's grim.
