Terry Jones, one of the key members of Monty Python’s Flying Circus, has admitted that he "only occasionally" found the comedy sketches funny.
The Welsh comedian, who played a maternal role in Life of Brian, said he would become nervous while watching some of the episodes.
“I used to watch in trepidation at things that didn't work wondering if no one would laugh,” he said.
The 69-year-old agreed that the animation between sketches was a “cop out” and added: “But Terry Gilliam covered the tracks so wonderfully”.
Jones was one of the six members of Monty Python, alongside John Cleese, Michael Palin, Graham Chapman, Terry Gilliam and Eric Idle.
It ran on BBC for five years between 1969 and 1974 and the group went on to make films such as Life of Brian and the Holy Grail, which earned a cult following.
However, the latter initially received a poor reaction.
“The Holy Grail was a disaster when we first showed it,” he said. “The audiences would laugh for the first five minutes and then silence, nothing.
“So we re-cut it and re-cut it and took out things like wind noises and the rustle of clothes because we thought they might be drowning out the comic pauses.
“It wasn’t until we played it at a film festival in LA to our first proper paying crowd that we got laughs, probably because we got there late and didn’t have time to tell anyone how on edge we were about it all.”
When asked if the six were still friends, Jones said: “Friends, for the most part, though we all wished Eric's Spamalot had been more successful.
"Especially John and myself - we need the money.”
Jones, who had his third child in 2009 with his girlfriend Anna Soderstrom, is currently working on a science fiction comedy film.
