The play that took the Edinburgh Festival by storm last year finally arrives in the West End today. Disco Pigs, Enda Walsh's exuberantly performed tale of a pair of teenagers out on the razzle-dazzle in Pork City - the fictional twin of Walsh's native Cork - is as beguiling as it is baffling. Pig (Cillian Murphy) and Runt (Eileen Walsh) communicate in their own oinky baby language and dream of a Tamworth Two-style escape from the deadly adult world that awaits them.

The Playhouse has struck gold with Steve Brown and Justin Greene's Spend, Spend, Spend!, a musical based on the life of Viv Nicholson, the Castleford housewife who honoured her pledge to "spend, spend, spend" after she won the first Pools mega-jackpot in 1962. It might be a heavy-handed cautionary tale for these Lottery-crazed times, but the cracking tunes and cheeky lyrics pay due homage to the complexities of a woman who dared to live for the day.
