Did you know that a fairytale kingdom has popped up in Highgate? Classic Broadway musical Once Upon a Mattress has just opened at Upstairs at the Gatehouse, and critics have fallen in love with Beth Burrows' Princess Winnifred, not your typical fairytale princess. We've rounded up some of our fave reviews.

In the final instalment of our "Once is not enough" video series, we have to take another look at the official show trailer. ONCE is like the best pub lock-in ever - and this captures the mood perfectly. (Last chance to enter our competition by Friday 6 March!)

We continue our "Once is not enough" video series with this sampling of ONCE's 16-strong actor-musician cast in glorious all-playing, all-singing action onstage at the Queen's Theatre, Hornchurch. (You can still win tickets to see them all live in our competition by 6 March.)

We continue our "Once is not enough" video series with this recently released version of Dan Healy's Irish street busker Guy from ONCE imploring listeners "Say It to Me Now". There's much we want to say to him, starting with 'wow!'. (Don't forget to enter our competition by 6 March!)

We continue our "Once is not enough" video series with this recently released version of the haunting "If You Want Me" from ONCE, sung by acclaimed Guy and Girl, Daniel Healy and Emma Lucia. (Psst. Have you entered our competition yet?)

To coincide with ONCE's first UK tour - and our competition to win tickets - we're embracing one critic's sentiment that "Once is not enough" to celebrate this musical, with our new series of videos about the show. First up, watch, listen and swoon to two versions of the Oscar-winning song "Falling Slowly".

It's won Tony, Olivier and scores of other awards around the globe. Has it also been winning the hearts of critics on its first-ever major UK tour? Short answer: yes! We've rounded up the review highlights and there are a whole bunch of ★★★★★!

In the upcoming revival of classic Broadway fairytale Once Upon a Mattress, Beth Burrows stars as Princess Winnifred. It's a role that's famously been played by American comedy legend Carol Burnett, Sex and the City's Sarah Jessica Parker and Hollywood's Zooey Deschanel. Watch them in action!

After forthcoming 2019 productions of I Do! I Do! and 42nd Street, Upstairs at the Gatehouse continues its string of Broadway revivals in 2020 with a brand-new production of Mary Rodgers' rarely seen fairy-tale musical comedy Once Upon a Mattress in March, starring Offies nominee Beth Burrows. Tickets will go on sale in late November/early December.
