My wife and I saw Ken Dodd "live" about 30 years ago and purposely went to see him again 3 years ago so that we could have a lasting memory of him. His performance started at 7:30, then we had a half-hour intermission at around 10:30 and we left the theatre at around 1am. Although he was 87, he was just a non-stop joke machine, who didn't fluff a line. He was giving another performance over 100miles away the next evening (same day we left the theatre). We've seen almost all the current crop of "known" comedians perform live and Doddy deserves his status as a genuine comedy genius and performer and he set a standard all other comedians must aspire to reach.
When he was asked about his singing:
Q: "How was your voice trained?"
Doddy: "On newspaper".
