Once a Catholic, a tale of life at a convent school in north-west London in the Fifties, followed three young girls' journey into womanhood at a time when just kissing a boy was deemed a mortal sin.

It was an amusing enough romp - particularly for those educated at a time when the threat of hellfire and brimstone were regularly employed to keep hormonal schoolgirls in line.

However, one might question the play's relevance to today's audience - both non-Catholic and Catholic - now nuns are a rarity in the teaching profession and, I'm told, the Catholic God is a tad more merciful and forgiving.

As well as being somewhat dated, the play was also disjointed and, it could be argued, better suited to the screen than the theatre. The first half lacked focus; it was difficult to see whose story we were following in a class made up only of Marys. Moreover, the play had the feel of a fly-on-the-wall documentary. We were observing characters who had made little progress by the end of the hour and 45 minutes.

However, there were some good performances, with the nuns sufficiently scary without resorting to over-the-top hysterics - something Father Mullarkey should have borne in mind in his rant about the Catholic Church as the one true church.

And apart from a few fluffed lines, Mary Mooney, Mary McGinty and Mary Gallagher were all believable as teenagers torn between their natural urges and the teachings of childhood.
