As the group’s sell-out reunion shows in Greenwich last year demonstrated, Monty Python is still a big deal.

And Spamalot, the musical ‘lovingly ripped-off’ from the team’s classic 1975 Monty Python and the Holy Grail, still has audiences rolling in the aisles on its national tour.

It is at Bromley’s Churchill Theatre between April 20 and 25.

Actress Sarah Earnshaw, who plays the Lady of the Lake, said: “We get a lot of Monty Python fans come to see it and they know it better than we do because a lot of the scenes are lifted from the Holy Grail.

“What’s great about Spamalot is you don’t have to be a Monty Python fan to enjoy it. It appeals across the board, really. That’s evident from the response we get.”

As well as fan adulation, the tour has also received strong reviews.

Sarah said: “Often the shows that the public loves, the critics don’t love as well so it is great to be in something that pleases both.”

After debuting in Broadway in 2004, Spamalot was a fixture in the West End for a number of years.

For the tour, Python Eric Idle and John Du Prez have written an entirely new score and stars Joe Pasquale as King Arthur and EastEnders’ Todd Carty as his dim man-servant, Patsy.

Of the show, Eric Idle said: “Spamalot is fun. The new production is funnier, it’s more like a Python show. There are new costumes and new sets and a new director (Christopher Luscombe), so it’s just got a whole different spirit to it.”

Though Idle is no longer involved day-to-day, Sarah said: “They regularly update the script with topical references, just to keep it up to date and the audience interested. Now we’re on tour we do include local references as well, which always goes down a storm.”

The Lady of the Lake has previously been played by the likes of Bonnie Langford so it was a nerve-wracking role to take on for Sarah, who first did so in the West End in 2013.

She said: “It’s a big responsibility.

“A lot of great people have played the role before me and you feel like you have big shoes to fill, which you do. I sing lots of the major numbers in the show as well, so that’s quite a responsibility vocally.

“I was very nervous about it but when I started rehearsals, the creative team are so lovely and supportive that all that melted away.”

As well as being a blast for the audience, Sarah said Spamalot is also fun to be a part of.

“We have been on tour since January so we’re a couple of months in now.

“We’re having a great time. It’s so much fun. We get to work and it is two hours of laughter and gags and fun, it’s like it’s not work. We are having a great time.

“We have an absolute ball doing it. We’ve got a really lovely cast as well and we all get on well outside of work as well and that always really helps.”
