The Sister Act UK tour has arrived at Norwich Theatre Royal and it is nothing short of a blessing.

The uplifting musical is the perfect tonic to the January blues as it follows disco diva Deloris Van Cartier (Sandra Marvin) who witnesses a murder and is then placed in a convent for her protection. 

But being tasked with blending in is no mean feat for Deloris and she leaves Mother Superior (Lori Hayley Fox) begging for divine intervention when she appears to be leading the other impressionable nuns astray.

But Deloris' arrival turns out to be a miracle in this celebration of sisterhood and friendship as she transforms the out-of-tune choir, putting it mildly, into something sent from the heavens.

Sandra Marvin, who has many West End credits and also played Jessie Grant in Emmerdale, was simply sublime in the title role.

Her vocals were as smooth as butter and her powerful voice filled the auditorium as if it was a gospel concert.

Songs that particularly stood out were the very catchy It's Good to be a Nun, triumphant anthem Raise Your Voice and technicolour finale Spread the Love Around - where the audience was in the presence of the Pope himself. 

The show features original music by Oscar award-winner Alen Menken, who also worked on Disney's Aladdin and Enchanted. 

The musical is based on the iconic 1992 film starring Whoopi Goldberg and the stage elevates it to a whole new level - though I did miss the song I Will Follow Him.

Lori Hayley Fox had a fabulous turn as Mother Superior as her tough exterior melted away and West End star Lizzie Bea was a hip-popping revelation as Sister Mary Robert.

Graham MacDuff as police officer Eddie was ace, particularly with a three-layer quick change you would blink and miss, and the trio of criminals TJ, Joey and Pablo (Bradley Judge, Tom Hopcroft and Damian Buhagiar were electric on stage together.
