If you have a fondness for seriously demented nuns and off-the-wall humour, this is for you. Tim McArthur

(co-writer with Rich Hough) in the person of Sister Mary is a kind of English Dame Edna Everage gone beserk.

She longs to be in The Sound Of Music and when offered a role by Dame Andrew Lloyd Webber gives perhaps her most innovative performance as Sister Bertha singing How Do You Solve A Problem.

The Sister also tears apart Paul McCartney's Let It Be and songs from Joseph, Mamma Mia, Annie. No show, no turn is left unstoned and she reserves a special role for Elaine Paige. McArthur's version of "Memory" is a gem.

The audience are bewitched by McArthur's deadpan, endearingly innocent charm and his vigour. He tells them to join in the ridiculous songs and they do it without question.

He has an incredible relationship with his piano player, Brother Matthew, performed by James Adler, who not only plays a neat piano and is a great foil, but is a funny man in his own right.

Every night McArthur has different celebrity guests. Comedy talents like Tony Slattery, Helen Lederer and Sheridan Smith are scheduled to appear later in the run.

This is a refreshing, totally undemanding evening of lunatic comedy. Leave critical and intellectual faculties at home.

Until June 9.
